Hi there I hope someone can give me a glimpse of hope hear when I go to start the car I have to wait like 45 sec until the fuel pump kicks in and then I turn the key to start and it will start just fine. Once it's warmed up it will start right back up. When I leave it set overnight I have to follow the wait procedure again.I have replaced fuel pump, fuel filter. Fuel relay, cap and rotor, and I have been a mechanic for quite a few years and this one has me puzzled any ideas

It could be an array of things, did you check to make sure that there are no fuel leaks as this will cause your fuel to go back and not stay pressurized for long periods of time. Also, if there is no leak, ten it could be some sort of connection that is not making contact until things warm up in your vehicle. Check all of your wires when it is cold and gives you the initial problems. Have you checked the fuel pressure regulator? I do not know what you have done and hope these ideas may be useful.

I believe your problem rests in the ECU. Encased inside the plastic covering is a circuit board covered with a protective layer of jel. If you remove this protective coating and access the circuit board you will find a collection of computer components. Your problem rests with the three capacitors on that board.

All you need to do is to purchase three of the same capacitors - available at Radio Shack and other electrical suppliers - and swap them out. Of course, this means desoldering the existing connections on the old ones and then soldering in the new ones. Once completed, your troubles should disappear.

The total cost of these capacitors should be less than $7 and it's not as difficult to do for a DIYer. What do you have to lose. If it doesn't work, you've lost nothing since the ECU wasn't any good anyways.

I did this and I have no special talent other than a curious nature. There are better instructions available on the net in Jeep forums.
