My son is doing redoing an 89 YJ with 4.2 and automatic.

There was a carb fire and it has been rewired but they can't get the engine to fire. There is some damage on the pigtail going in to the computer and it may need a computer.

Anyone have any leads on where to find one. He is scouring the salvages in Central Florida with no luck so far.

Does the Cherokee use the same motor/computer in the late 80's? There seems to be more of these in the junk yards.

Would appreciate any help you can offer.

Thanks

Rick

why not try the nutter bypass on it. Here is the link if you find out this isn't the problem you can go back to the way it was. http://www.4x4wire.com/jeep/tech/electrical/jn-ignition99/
Hope this help the bypass can be done under the hood with two wires long enough to go from one side of the engine area or just do a set of jump long enough to try you might have some fired wire causing you your problem.

Any junk yard should have one. the Cherokee one is not the same, because it is FI not carbed.

I think I have an extra one, Ill take a look and see if I still have it.
