I recently parked my 1997 ZG Jeep Laredo 4 lt Petrol. only to find it just never to start again, It would crank over but just not start. After several tests by my mechanic neighbour. He was 100% sure I had a faulty PCM. I purchased a second hand pcm with same numbers out of a running vehicle. Now it starts perfectly for 2 seconds then shut down.?? (with the old pcm it would not start at all)
During this whole process I had to get a new battery also.
The key fob (black key) works fine, but I think it may be the engine immobiliser ?. shutting the engine down. I have also disconnected the battery to drain any charge and hopefully reset the pcm and/or enable the immobiliser. This did nothing.
I have no flashing red light on dash (never have had)
I had an Auto electrician out with his scanner and he could not work out the problem and left saying "he would have to do a little research" (that was 4 weeks ago.He's not coming back!!)
Can somebody please help me with this issue in getting my only transport up and running again.
