I buy all my filters from Western filters in Sydney. CrD filter kits

G'day, I haven't heard of filter brands like Osk before, but I caution you with too cheap filters..... Indeed I'd be looking at water separator in that case. 3" exhaust on CrD should be OK however a lot of people use 2.75" exhaust with very good result indeed better because 3" appears to be too big to maintain correct back pressure. Beaudesert does make the entire set. ===> https://beauexhausts.com.au/product/patrol-gu-3l-exhaust/ The only issues with CrD is when people attempt to block EGR... causes MIL to come on. Regards

That hose look clear so to me it doesn't have an issue with air in the fuel. However those ICV% are very low. At idle it should be around 50% as a minimum. Mine has around 63% with additional lift pump. ECU Talk creates log of your gauges as A CSV file is a Comma Separated Values file. All CSV files are plain text files, can contain numbers and letters only, and structure the data contained within them in a tabular, or table, form. I open mine in LibreOffice spread sheet to have nice collums. See here ==> https://www.ecutalk.com.au/ecutalk.aspx The key is to select only a data (gauges) you need otherwise it is too much and can get corrupted. Log file is created usually in the same directory ECUTalk runs from..... B/R

Oil pressures look fine, however which model year is yours? If it is 2007 onwards then ECM is measuring the actual oil pressure from RHS unit. Oil Pressure is monitored via the ECM with the utilisation of an Oil Pressure Sensor which is located at the RH rear of the engine. In addition to the Oil Pressure Sensor there is an Oil Pressure Switch located at the LH front of the engine, above the oil filter. This switch will ground & illuminate the ‘red oil can’ warning light when there is close to 0 Oil Pressure. The above mentioned Oil Pressure SENSOR is connected directly to the ECM. If the ECM measures specific pressures at certain engine speeds & temperatures, the ECM will signal the Instrument Cluster to illuminate the RED OIL CAN warning light on the Instrument Cluster. Regards

Hello, I agree, just gauges would be enough so you're aware what is going on. CrD uses different ECM controls therefore playing around with various aspects of insufficient controls from previous model is probably pointless. But I'd check how does glow circuit behave and if it does the same silly behaviour as in Di I'd fit extra timer. Having additional means of seeing coolant temp (via Scangauge) if possible is also a bonus. EGR block is also problematic on CrD models. In any case fitting boost control could improve performance. Regards

Read my previous post fully, then search Dronus4x4 posts about NADS on this forum and on patrol4x4.com as well as GU2 user archives and posts about external lift pump there. VP44 can suck its own fuel from the fuel tank however Bosch made provision for external supply pump (lift) in its reference design as vane type supply pumping section inside the injection pump is very inefficient at lower RPM under heavy load. As for that "o" ring there is no harm putting it there but most Patrols lost their on first filter service as dumb mechanics don't pay attention and Nissan also claims it is not needed. To bleed the fuel system is self bleeding but gets overloaded if is it continuously sucking air. Prime up until no air is coming out of the filter to pump hose than connect hose and prime more until pressure relief valve opens or priming button goes hard. Cheers

Hello, Finally you're cooking with gas..... The most important gauges are: RPM, Water temp, Battery V, Throttle V or %, Injection Timing % (duty cycle), Air flow, Barometer, Fuel Temp, VNT Turbo %. MAF Voltage seems a little higher for idle.... If Injection Timing % is bellow 40% you have air in the system or problem with fuel. Normal operation around 50-70%. So in yours, barely reaching 41% at idle yes you have problem with fuel delivery. add external lift pump and you will find the leak quickly. However you MUST carry out SPILL/OVERFLOW LINE modification otherwise you will pump fuel backward in to the injectors and cause major failure. In this imbecilic design of the injection pump fuel is used to cool, lubricate as well so not enough or starvation will destroy the injection pump very quickly. Fuel starvation is the most common reason for the pump failures. One way to mitigate is to add external lift pump like carter 4601 to Walbro 13-2 ....The arseholes from Bosch who ripped this design from the UK have caused so much heartache and financial damage to the owners of those cars with that abomination VP44 radial injection pump. But generated a handsome profit for the manufacturers! Just search VP44 failures on Internet! Fuel temp is also very important keep in mind it depends a lot on ambient temp but continuosly above 60-70 C will spell trouble for the pump. Yours doesn't show turbo boost (absolute pressure), mine does so yours is series 3 and less. Air in the fuel is very difficult to diagnose, one thing to remember is that if the fuel pipe from the tank is compromised then air will get in. Another source of air getting in is primer on the top of the fuel filter. I'd also check hoses on the fuel tank, under the cargo space is a cover to reach to the pick up. One resort is to use a jerry can and rig up temporary fuel delivery to by pass pipes and tank to see if the air is sucked in at filter housing. Or if you have access to air compressor and regulator trick is to remove fuel line at the pump, block it with a bolt or something then remove fuel line at the tank pickup and pressurize the fuel line and find where air is leaking if any, or get a spare tank cap and drilled and fit airline fitting to it. (that's how it is done by some workshop or some manufacturers. Remember low pressure only (max 100 kpa ). I'd avoid driving the car until you identify why Inj Timng C/V % is low. If you wish, warm up the engine and go for test run around the block and check what you get at WOT (wide open throttle) Anything bellow 30 is massive trouble! You can log the data from those gauges in ECU Talk in to CSV sheet and open it in Spreadsheet app of your choice or just text editor. Set up log for the Inj Timing C.V %, RPM and throtle % so you can collate the data and see instead of starring in the laptop screen while you drive. Regards

Well how far away? As long as it is in the engine bay you should be OK.

With such temps in the morning I'm sure glow plugs are not up to the job anymore.... You will need to check resistance accross the positive terminal of the glow plugs and its body (or nearest ground). So you will have to remove intercooler and buzz bar. If you find that values are out that means removing them and inspect visually if the tips are still there. Metal glow plugs are cheaper but wear out very quickly about 20k so the timer mod is absolutely essential indeed it is in any case. The stupidity of glowing for 5 mins. Ceramic tips glow plugs last longer 100k but are way more expensive but with the timer mod as well you'll probably don't need to replace the next ten years. Nissan also wnat you to replace them with right ones too. I can confirm that the ones with blue mark are ceramic type. See bellow.

I would not loosen injector line! The only way to find out is connect clear hose from filter to pump and check for air in the system (bubles) Also are you sure your glow plugs are up to a scratch or actually work. To me it looks more like glow plugs if it starts right away when warm. How cold is in the morning? The bolt on the ECM plug, mine has been broken for years, I broke it undoing it with just little ratchet. Plug is held in place by giant cable tie wrapped around the ECU. Regards

I think it is harness to the injection pump... You've fiddled in there and now disturbed something for good. 0703 DTC is about ECM to IP comm which means voltage range is out due to either shorted wires or broken wires.... See bellow how to check:

When you scroll up to my earlier posts I added info in regards to crank sensor e.g. gap, installation/removal ..... Regards

It would be possible source of your trouble. Fix and test. It is cheaper then throwing expensive injection pump at it. Consider adding external fuel lift pump but remember to modify injector overflow/spill line. Regards

That code is general trouble from pump ECM and it has a few reasons/conditions. Quote: Injection pump control unit has an on board diagnostic system, which detects malfunctions related to sensors or actuators built-into electronic control fuel injection pump. These malfunction informa- tion are transferred through the line (circuit) from injection pump control unit to ECM. Now from past experiences I know that code is set e.g. when there is air in fuel as it affects pumps ability to do fuel metering....so it guesses. Its called "garbage in causes garbage out" in other words wrong input means wrong outputs. Regards

I think OP is no longer around, his last visit was in 2014.... Cheers

Yes you will need that cable for it to work with ECU Talk software. In regards to injection pump: Search online for testing VP44 injection pump (and its Zexel clone). the issue is that the pump has its own ECU and has its own diagnostic codes which are not visible to main Engine ECU (ECM) so to make diagnosis you will need Bosch scanner for such pumps (only Bosch fuel injection diesel specialist have them) and only then I'd say needs the new pump. If you are feeling adventurous you can create your own K line protocol OBD2 custom interface but research it thoroughly. You will also need to create the custom injection plug (PSG5) and OBD2 plug to make that harness and then another serial USB to OBD2 adapter to connect to it! (Not ECU Talk cable) See this diagram In the zip file attached is what is claimed as VP44 diagnostic software. I came across it but never used or tested it. So thread carefully. Also confirm that wiring on yours is the same as example provided. Note on the pump code 0705 : You will get it when there is air in fuel, suspected points of entry can be priming button on the filter housing, incorrectly fitted fuel filter, or dodgy fuel lines. I'd confirm the grounding point on the inlet manifold as they can be suss, I'd also make sure the main ground cable from battery to chassis and engine block is OK. Indeed Patrols are notorious for bad grounding so if in doubt run your own extra ground cables from chassis to body and battery to body/chassis/engine. IP harness to check/follow location whole.zip

This doesn't compute cause 2001 Patrol with ZD30 never had OBD2 plug. It had grey Nissan Consult II. Nissan started with white colored OBD socket from 2004 series 4 however it is still only wired up as Consult II interface. Not compliant with OBD2 protocol. That happened with the arrival of common rail ZD30 in 2007 onwards. Ecu Talk cables I have the OBD2 socket in mine and cable for it ==> Y61 ODB2 So, If you have those mods you must take control of the turbo charger away from the ECM or must limit max boost bellow 15 psi and bellow 11 psi at or bellow 2000RPM. Thats why Dawes valve or Tilix valve is used to limit max boost, to control spool up rate needle valve is used ...... It is still not enough so basically keep the accelerator pedal light bellow 2000 RPM and if/when it limps learn to quickly release it and re-apply.... I suggest you search on these forum thread about NADS.

ECU Talk will never work with OBD2 adapter sorry incompatible protocols! You will need to use Consult II interface/adapter those cables are available from its website. I'd be lost without it. Code 0406 : An excessively high voltage from the mass air flow sensor is sent to ECM when engine is running. If there is NOT 0102 code present it is likely that MAF sensor is not faulty and actually measuring high air flow. Possible causes are: However above doesn't take in to account that you have: Blocked EGR, fitted 3" exhaust and left stock controller in the place. What that does is causing it to overboost and triggering safety "limp" mode in certain RPM range. This is well known to all of us who mod this POS. if you get 18 psi out of yours and that's why you are getting that code! Code 1003 probably cause it is either disconnected or other way electrically disabled, normally we leave it connected electrically and block the port with metal shim so ECU is none the wiser as it doesn't actually measure the EGR flow like on much later vehicles it just guesses so it is dumb and to our advantage. Code 0407 If you see bare wires then yes not good, I will attach some info on checking these codes, bare with me

Are any of these codes active? You really need to see what ECU is doing and its sensors. ECU Talk software with its Nissan Consult II adapter cable can read the sensors in real time so you could use it to pinpoint cases. Pump harness is reasonably accessible however I'd not call it easy. Regards

Firstly I'd would make sure that harness to injection pump is OK. There is a short piece going from engine interface bracket to pump and it is not uncommon for the wires to wear out inside the conduit there. That dumbo mechanic cleaned the plugs so he disturbed the harness temporarily fixing it. Any codes? Anyway you need to specify which model is yours, year or series perhaps.

G'day, Well you probably already know the answer, you need to replace the priming bulb. The other way to get going is to pre-fill fuel filter and then hope it (engine) starts and finishes the priming itself. The additional way could be to try one of those 12V electric fuel transfer pumps to get the fuel up. To check that priming bulb is good you could fill a jar with fuel and see if the any action happens. Regards

Hello, I'm not familiar with Y61 auto transmissions but as yours is fully OBD2 compliant I'd try to use OBD2 scanner to find out if transmission temps are displayed. If they are then I would not proceed with installation of hardwired gauges. Certainly I'd not pay 800 bucks to have one installed (does it come with golden bezel too?) OBD2 BT adapter (ELM327) is about $10-20 bucks, Torque Pro app is about 10 bucks so to test/try is cheaper proposition. ScanGauge 2 OBD2 reader does have some issues with reading temps but it is supported allegedly Nissan Patrol Scangauge Still cheaper then 800 bucks and it gives you way more gauges then just transmission temperature. However you will need to experiment. If you don't want hassle and just read one gauge then have it installed hardwired. Regards

G'day, To be able to better identify these type of faults (ECM to pump module DTCs) you will need Bosch scanner which directly connects to the pump. If this issue wasn't there before fuel filter change that would mean you have air in the fuel and possibly because filter fitment introduced the air or is not sealing properly or leaking through priming button. Regards

Try this ==> but with caution as Ni$$an is typical with how one can't identify which version one has. I looked in the manual and the way they list these glow plug circuits is either for cold areas and except for Australia or just but there are two fundamental versions.... since yours has been converted it is even worse to identify. Bellow is an example for "cold areas" whatever that suppose to mean all places but Middle East and SE Asia and Africa? Cause if you live in Darwin AU you don't need glow plugs but if you live in Tasmania or Victoria's High Country you definitely need glow plugs for cold areas.....This entire control system BS I would re-wire to manual control where I get to choose/decide if I need to glow. However TD42 being indirect diesel injection system those are notorious to require glowing even in mild temperatures..... this system is over complicated as it has pre-glow pre start and then post glow after start (for emissions) ..... Regards

G'day, Welcome to the forum. Feel free to explore, ask questions and share ups and downs of Patrol ownership. Regards
