Has anyone had an issue with the Fuel Shut Off Solenoid on a GU Y61 4.2TI Anti Thieft Fuel Pump?
My Wagon has been hard to start when warm, Just cranking and not firing. When I leave it to cool or tap the pump and linkages then try again she sometimes will start, but over the last week has gotten worse.
Has gone to United Fuel Inj to get it replaced, Fingers crossed that fixes it or its a $650 lesson...
Anyone had the same probs....
Cheers

Hey mate, it might be the problem, but under the code hoping solinoid there is a "normal" solinoid. If they are going to the effort of remooving the anti- tamper screws etc, i would leave it off and wire up a switch to the std one.

Thanks for your help Pete! That's exactly what they have done. Got the injectors and a dyno done at the same time.

Would this work for a 4.5 Carby (tb45s)

Hi Guys, Sorry to resurect this old thread but do you have any idea if this is the same type of system on a carbed 4.5? I have a swb middle east spec (I'm in UAE). This thing has been driving me crazy with a two headed problem.

First problem: NATS engages 8 out of 10 times I try to start it. I have to turn the key off and on until the light does not turn on, then it will start.

Second problem: The engine will just die periodically, mainly when offroading(dune bashing type). Sometimes under load sometimes not. After it dies it usually starts(sometimes the NATS engages, or not) but it is slow to start after this and there is usually black smoke in the exhaust. Today within one hour it stalled about 10-15 times

I know it doesn't seem like this is related but several times I've had the key and NATS resynched and it will work well for awhile, no engine dying and not NATs issue so it seems they may be related.

I would love to just disable this solenoid on mine as you have if this is possible.

Thanks,
Mark

4.2 GU anti theft inj pump DRAMAS

I have a 2005 GU Patrol ST 4.2 and it is doing exactly the same as EUCLA69 but I cant bring myself to removing the inj pump to fix it as there must be some sort of way to bridge it or bypass it. Does anyone no of information of why 3 wires to the inj pump fuel solenoid and what they are for I know the middle wire has power when key in on position but thats as much as I know. The engine still winds over but wont fire???
Can anyone shed some light on this drama.:bowdown:
Trusty old 4.2 no electronics, fooled me!

There's lots of info if you search for nats. Also 'intermittent no start' and nats fault. Some threads below.

The anti theft cant be bypassed. It has sheer bolts holding it on. Once removed, its just a solenoid underneath that needs a 12v supply to make it work. The hardest bit is removing the anti theft device.

I pulled pump off today and removed nats solenoid and now my gu iv runs off a normal steel key

Can this solonoid arrangement (with NATS fitted) affect the way the engine shuts down?
Trying to track down why TD42ti runs on every so often
Nissan claim they replaced shut down solonoid at ~ 5000km. After reading this I really doubt it as the pumps never been off that I know of. Now done 160K km
