Re: Grand Cherokee wk not starting, Immobiliser fault??
No the starter will not crank by The key, but it will crank fine if I touch the contact in the starter relay, I tried doing this with the ignition on but it doesn't fire up, so I'm presuming the immobiliser is not letting the injectors open,
The immobiliser light stays on most of the time but I have read it should go out after 3 seconds.
I've had a locksmith out to reprogram both keys, his computer said they were both programmed successfully, but still won't start :-(
