NATS Immobilizer light staying on??

[MudRunnerTD]

Hey guys (Rodney ) I noticed last week that the little red light on the top of the dash in the GUIV is staying on sometimes when I'm driving? Not all the time? If it stays on it seems to stay on for the journey though until I turn the car off.

Should I be concerned? Is there some hidden message? No idea!

Thanks in advance.

Hey mate.

You have a problem with NATS, more then likely the control module on the back of the injector pump.

Do you always use the same key?

Hi Rodney,

Yeah mate I only have 1 key. It is not a program key though. Mine has a separate fob.

Just called the RACV and they are an hour away maybe

The fob has nothing to do with NATS.

In the black plastic part of the key is a chip. The NATS needs to receive the correct signal from this chip before the vehicle will start.

I don't think this will be your problem because you only have one key.

Hi Yendor

Yes mate i always use the same key, and as for little red flashing lights on top of the dash, i don't recall seeing one unless it's hidden under the dash matt, anyway i had to get the car towed home so now it's in the shed i will be able to check out the fuel system right through to eliminate that issue and look under the dash matt for red flashing lights and hope NATS is not the problem.
One other thing is where is the fuel pump and is it electrical or mechanical as i have never had to deal with any fuel problems before, come to think of it i brought the car with approx 28K on the clock (now 210K)and never had any problems what so ever in the 14 years i have had it so i cannot complain, and thanks to everyone for the suggestions now it's in the shed i can have a proper look.
Cheers

Yendor is no longer here mate. The fuel pump is on the drivers side of the motor under the power steering pump. It sounds like your NATS mate. The pump is mechanical and a significant job to remove and refit. As you read this thread I went at mine with a wood chisel mate!!!! A Very big deal!!

There are a couple 9f other threads on the forum about the task of you have a search but fundamentally it is laid out here.

The red LED light will be under your dash mat for sure basically directly in front of the driver.

Read this thread a couple of times mate. Happy to chat.

Thanks MuddRunnerTD

I found the red flashing light, my dash matt has been on there forever and i completely forgot all about the flashing light under neath it, as yes it stays on if i am lucky to get the car started and i have two keys and tried them both with no change so it looks like i will be up for the big bash to fix my problem.
You would think someone would make an exchange pump without the bullshit on it but knowing nothing about pumps i guess it's not that easy or cheap.
Any way i will red through all these posts again and i might get the courage to attempt it.
Cheers Guys.

Good luck mate. Yes I took some balls mate. A new pump from UFI is about $2700 plus fitting.....

Edit that!! Damn it to hell! It has just left me on the side of the bloody road!!!

Just done a 14 hour day and having dinner at 12:30am at Maccas and she won't start.

Anyone still online that can tell me how to override the imobilser?

The only way to bypass NATS is to remove the module on the injector pump and connect ignition directly to the solenoid.
