  1. 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:
  2. When you scroll up to my earlier posts I added info in regards to crank sensor e.g. gap, installation/removal ..... Regards
  3. 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
  4. 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
  5. I think OP is no longer around, his last visit was in 2014.... Cheers
  6. 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 als
  7. 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 b
  8. 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. Wh
  9. 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
  10. 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.
  11. 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
  12. 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 S
  13. 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
  14. 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 f
  15. G'day, Welcome to the forum. Feel free to explore, ask questions and share ups and downs of Patrol ownership. Regards
