Hello,
I have a 1990 Jeep Cherokee Laredo, 4.0L, 4X4 Automatic. January of 2007 I started having problems where it would occasionally not start. It was as simple as the engine turned, but didn't appear to be getting any fuel. I would give it a shot of ether, and it would usually start right up.
Then at the end of the summer, It started actually having no spark. I could leave the truck alone for a few hours, come back later and try and it would usually start right up.
As the Fall progressed, the starter seemed to be intermittent, so I replaced it, only to find that something else is wrong, and that the truck would then only start with the key about 20% of the time. Then, the fuel pump stopped working. I had it tested, and they told me that the pump was fine, it needed an ECM, so that was replaced as well. This seemed to solve things for about two days, then back to the same old crap. By December, I had to start using a push button to start the truck because it hardly would start with a key, and was having more and more issues with the ignition.
Now, the truck does not start with they key except maybe one a month, randomly dies and won't start because of no fuel/spark. What could be the issue? I'm a mechanic, but not great with electrical crap.
Thanks guys
