None starting grand cherokee wk 3.0 crd, immobiliser fault ???
I have a 2006 WK 3.0 crd that will not start.
The last time it was running it started for a few seconds then cut out, apparently if you use an invalid key it will do this. I have tried both keys but neither will turn it over at all.
I have bypassed the starter relay and the starter turns over fine.
Code reader showed faults on glow plug module and gear shifter module, both these parts have been replaced and the fault codes have not come back.
I have had an auto locksmith out to it who reprogrammed both keys and the computer said both keys were then registered ok.
Ive noticed that most of the time the red led immobiliser light stays on but it should only stay on for 3 seconds.
Any help would be greatly appreciated.
Ive already spent hundreds on it fixing the two modules and locksmith call out so this is my last chance before getting it towed to the rip off dealers.
