Gu key immobilser issue.

[SuperGQ]

I have a 2001 gu td42t with the transponder in the key.

I beleive this activates/deactivates the fuel pump.

At the moment intermitemtly the car won't start. (yes it cranks over fine)

Took it to nissan and hooked diagnostic to it and it had logged invalid key codes.

This can be fixed with a new key and or reader unit.

Does anyone know how to bypass this?

I bought a td42 for the reliability but it seems even a pissy key issue can stop u, it would be handy to know how to bypass it when I'm in the middle of nowhere and it happen again.

I had the code drop out of a key and Nissan re-coded it for free.

I priced a key blank today $100 + $45 apparently for recoding! Laughed and walked out as another nissan dealer does it for free.

Apparenty its common for this code to drop out on Ebay or cheap keys, but from what I read on patrol forum OEM keys are this shiznit

Yeah but can happen to Nissan keys as well.
Try to keep them away from magnetic fields also even dropping them can make it happen.
Best to have the spare key with you if you go away. Be s**t to be stuck in the bush with a buggered key.
(although the only reason a 4.2 would get towed back home hey Bogged)

I just got told by nissan that it was going to be $180 per key to purchase,cut and programme.

Bit expensive but it has to be done.

Still would like to know how to bypass this incase it happens in the middle of gods great country.

Any ides?

Which dealer?

Jump on Patrol4x4 forum and have a look, theres a bloke on there that does alright prices on shiz, hes in Melb.. Then you just need programming. IF you need the remote door opener he can do them too and includes instructions on how to make it work without nissan dealer

Good luck trying to bypass the NATS system, if you work it out let us know!
if you have your injection pump rebuilt with out the fuel cut out system fitted then you will get around it.
The system uses a coded module and a cut out solenoid on the back of the pump, and good luck trying to remove that too.

Trucks now been a nissan for 5 days, they reckkon its now not the key but a wiring issue.
There pulling the dash apart and computer out to find the problem, which they think is between the computer and pump, but still reads as a key error.

Gotta fing a bypass for this pump solenoid.

So this aint a warranty job is it? that could get scarily $$$$ rippin the dash out etc...

The module on the pump is probably faulty. we have replaced a few of them for the same fault

If anyone does find a bypass, it might be a good idea to keep it off the net for anyone to have access to, sux not to be able to start the car.....worse to have it stolen

If you can bypass the solenoid/key imobilised you still need the correct key to unlock the steering and crank it over.

Real thieve's will steal anything they need or want no matter what you do (imobilized or not), this stuff just stops joy riders amd honest people.
This would be to hard for joy riders, therefore it's just to keep insurance company's happy, and shit honest people like myself to tears.

Bring on the bypass if anyone knows!!!!!!!!!!!!
(Truck is still at no idea nissan)
