GU TD42i turns over but won't start

[Astro]

I have done a search and couldn't find anything useful. So please bare with me.

Had an issue this morning with the GU.

Had driven 15km or so then returned home, parked on a slight incline (nose up) and turned the engine off for a few minutes.

Went to start the engine and it wouldn't fire. Plenty of oomph from the battery, just wouldn't fire.

Called the NRMA, he giggled and wiggled some connectors, cracked an injector. I tried to start it while the injector was cracked and it started. I turned it off to try again. Nothing.

It got loaded onto the tilt tray and taken to my auto electrician because the consensus was that it was something to do with the fuel cut-off.

Any ideas ? ?

Does it have an engine imobiliser on it, if so you will have to get it reset, Terranno 11 did same.

[Astro]

Mmmm, I think so.

The auto electrician said he will put the diagnostic machine on it to see if has thrown a code. If it has he said it will be a job for the dealer to reset. Does that sound right?

Thanks for the lead Choppie

Does your Patrol have NATS? does it have the red flashing light on top of the dash?

When the vehicle doesn't start does that red light stop flashing or does it keep flashing?

Have you tried starting it with your second key?

There is No check valve between the back of the fuel pump and the fuel tank and only gravity. You might just be unlucky. Use the hand primer pump and pump until it is pressurized and give it a good kick. Mine does this a bit at the moment and I think I have other problems but you might just need to give it a pump.

Mine has been doing this since July. I have been doing a fair bit of research about it trying to Not have to rip the pump off. Use the hand pump and see if it will start. I have Never had to crack an injector.

Mine generally takes about 4 turns of the starter motor to fire up, on a bad day that could be 15 turns.

Yes, has the flashing light on the dash. The sparking is looking into the flashing sequences it should display.

I will take the spare key in to the sparky tomorrow.

Thanks

We had it started and running on flat ground. As the NRMA tech was packing up his gear, I turned it off, waited a few seconds, then went to start it again. Would turn but not start, so I don't think that is the issue. Could be wrong though. We'll know more tomorrow.

Thanks for input though guys

I am very interested to hear how this turns out for you mate! Very interested! I have not considered an electrical fault to be honest! if you find one then please share here!

Cheers

Your problem sounds like it's with the NATS , either the key is not being read correctly or the control unit on the back of the IP is not switching the IP solenoid on.

It will be interesting to see what/if any codes are logged.

If it is the IP control unit that is faulty this thread may interested you.

Thanks folks.

I've printed out these few pages of the forum and about to take them to the sparky, with the spare key.

Stay tuned.

I called into the Nissan workshop today and they said the problem is with the NATS, but they can't pin-point which of the 3 components is the faulty one. Should know more later this arvo.

Thanks for all your suggestions

[Astro]

Problem has been determined to be the solenoid on the rear of the fuel pump

[MudRunnerTD]

how much do nissan want for that??

[Astro]

Don't know yet mate. Should know more late Monday.

[Astro]

Got a call from the local dealership this arvo, said that the solenoid is working fine, the problem appears to be in the control module.

They can by-pass the module and have it running, just won't have NATS,

OR they could get me a price on a replacement module.

Who wants to guess how much $ $

[Yendor]

I'll guess about $1000.......I would just bypass it.

[Astro]

$8500 or there abouts. Nissan only sell the module as a complete unit with the solenoid and IP.

I knew Nissan stuff was dear, but feck me!

I am in the same boat right now and I am pretty sure it is the NATS that has demobilized the car. My light is flashing and when I insert either of my 3 keys it becomes solid red. Acording to the small instruction manual that comes with the car, that means the key has not been recognised. "Please go to your nearest Nissan dealer... ... ..."

I have a Haynes Manual on the car but I am that tired of that book, it has nothing more advanced than how to undo the bolts in the interior, does anyone have some real electrical diagrams on a GU 4.2TD from 2000.
