Thanks for your Help Rumcajs, Been trying to think what your name means, Rum can always just sip ?? Re my diagnosis of pump failure, I also spoke with Steve at ECPT who said in regard to NATS that if my dash lights cycle as usual being glow plug light etc then not NATS issue, even if no little red light visible? Checks I have done: Power to IP key on, yes Cleaned all Batt conn and new battery Fires with start ya bastard, yes Tried to run with pump hot wired, no good Checked all fuses, good retrieved codes 1401, 1403. possibly unrelated. swapped out MAF sensor Cleaned air filter and checked snorkel and intake for blockage Replaced fuel filter and primed. this seems it may have small leak, after start attempt it can be pressed again. I have done numerous start attempts with constant priming at same time to be sure fuel is up, so I feel that's not stopping it from going?? So I'm not sure of anything I have missed bar having pump scanned but no luck there around my parts Sth Coast NSW inland from Eden. Anything else I can do to be 100% sure, prior to pulling it out or having it towed somewhere to diagnose. I'm definitely up to replacing it myself but would be pretty annoying if it isn't the problem. I'm on about 90% sure its IP Regards Jo

Hi Rumcajs, Well It didnt run made a click sound upon connection and constant click/buzz after start attempt. Same sounds as when connected to harness but the buzz shuts off soon after start attempt with harness. So if I did it right the pump has failed. Not sure where to from here, Tow it to Nissan I suppose😕

Think I will give the hot test of pump a crack, I was a bit confused re the pin positions but now realise pump is installed on left side on the 6 cylinder diesels the blue chip article is talking about. If anyone reading this has tried it please let me know, I'm happy living on the edge but rather not fry it if possible! I will change out my filter and re bleed prior just to be sure. I'll post the results Jo

Hi James1, This thread is old I know, but I would love to know what you used to talk to immobiliser and make it accept new keys. Regards Jo

Thanks Rumcajs for those very detailed docs. I am thinking it may be best to eliminate the IP first as the testing for faults in other areas seems pretty hit and miss and alot of time required. Could you post the details required to assess if ecu component on pump is not fried. If I can confirm pump is still working and get it to idle then probably worth continuing. If not might be time to move it on. Regards Jo

I couldn't see numbers of fuses in engine bay, manual said 20A which are all good and checked the lot just in case. Rumcajs, Is it possible the 1401 1403 codes are showing because IP has been modified to remove Nats system on back of pump and hence why no blinking red light? Maybe codes have been there the whole time? I believe they dont turn engine light on? Jo

Hi Rumcajs, Thanks so much for taking the time to reply. Re the engine, was done prior to purchase, previous owner said same ecu and loom, I don't remember mention of pump, my guess is was drop in donor long incl IP. No idea on keys or if resetting was done. I have 2, tried both. Ive never needed to see $tealer and I'd like to keep it that way. I re checked 24, 25 both good, assume #50 is good, I'll check and notify if blown Jo

Hello Patrol people, After 7 yrs of trouble free use and now 380000ks the truck has decided to rest. Codes 1401 1403 which suggest NATS issue, 2001 ZD30 Di manual (2005 engine installed) I have cleaned all battery connections and battery is new, did start twice after install of battery but not since. Cranking fast. I have cracked injector pipe on #1 and fuel is present, cleaned it up and did it again, seems plenty of fuel. Pressure in filter housing seems normal and doesnt change overnight. I changed MAF sensor to one that came in glovebox with car assume its ok. I did put a bit of start ya bastard down snorkel and it fired up a little so not catastrophic fail I imagine. I have never seen on dash little red light people mention re NATS I'm not clear on how/what ecu controls on IP? looks like old school pump Seems odd to have fuel pumping with NATS codes I would of thought that fuel would be cut ANY ideas appreciated, 2 days trying to sort now, no results Thanks, Jo
