Removing the NATS in a Nissan Patrol TD42 2005

Hello,
Does anyone know how to remove/override the NATS engine immobilzer system for a Nissan TD42.
I took the car to the nissan dealer and they could not fix it and want to investigate it further costing probably alot of money.

The thing is, I think the car would be much more reliable if I didnt have to worry about it mucking up and not starting.

Any help would be great, I have purchased and waiting for the service manual to download, to have a look at the wiring diagrams to try understand the system.

I appreciate anyones experience with the problem of NATS.

I do recall a thread about people having nats reprogrammed and spending money replacing crap at the stealers only to find the problem eventually being a bad earth connection.
Their is also an aftermarket product for remote start car alarms available that produces a signal the same but i can't remember what it was called.

Oh Thanks for that, I will keep searching the forum. And look into the aftermarket product.

Viper alarm for $6 - 700 you get remote start and a smart start device to use your smart phone to lock unlock start ur car and if u want to use the gps tracking you can pay annually $60 $99 or $130 i just put 1 in my mazda its great remembers were you park and even has some other features like parking meter so you dont get booked
Oh and it also has the pre heat feature for diesels too

Alitis007...I am not sure this is going to help me with the Nissan Anti theft System, unless you have installed it and it overrides it?

Their is also another option from reading a thread on another forum i can't post links to here on the injector pump apparently their is a black box for the fuel cut of solenoid that has power earth and nats signal inputs or 3 wires then underneath it a normal powered cut of solenoid.
apparently you can just bypass the black box power the original fuel cut off and be done with the troublesome nats rubbish.
If you speak to an auto elctrician and explain it they should be able to help.

Thank you, will look for it!

Yes it can be bypassed. There is an electrical control unit on the injector pump that needs to be removed.

Hard part is, you need to remove the injector pump to do it.

Oh K Yendor this seems more positive! My husband is very good with cars, and is pulling his hair out with this atm.
Is it fiarly stright forward to find once the injector pump is off!
Can you be more specific? Have you by passed your?

I don't have the same engine as yours.

Yes it is straight forward just as described above, you remove the control unit and connect the ignition and earth straight to the shut down solenoid.

I was unable to find any pictures of the injector pump but heres how the system works and the wiring diagram.
