1993 Jeep Grand Cherokee limited won't start
My Jeep is 4.0 and i replaced the fuel pump and
the coil. It turns over and Everything checks out but
it still does not start. Driving down the road it
started to cut out and so i put the hazard lights on
and pulled over. As soon as i pulled over it stalled.
Thought it might be the fuel pump but i replaced it.
still no starting. Help
Before replacing part,s at random,you need to check the fuel pressure and for spark at plug,s this will narrow it down,with out checking these two thing,s you will not know.
I should have said i double checked everything including spark and fuel pressure.
If you have spark and fuel,you probably have a timing issue.
Try cleaning all your grounds, even the brained straps you see in the engine bay, then check to see if security device has engaged, you can read my other post for that if it has engaged
Your pcm could possibly be your issue. I have a 96 and I've found many people with same issue. Inside the pcm, there are contacts that come loose over time. You basically take out your pcm, open it up , and determine what contacts could be soldered. Many videos online on this subject. You can also go the ghetto fabulous way and cram something between your coolant resevoir and your connectors going into your pcm and see if that may make a difference.
