Okay, everyone......I'm probably the biggest moron in the Western hemisphere. I've been jacking with this thing for weeks, have replaced the injectors, fuel filter, taken the upper intake off several times, opened my wiring harness and chased wires from the computer to the injectors...................

All because I had #2 and #4 reversed at the distributor cap. It's running like a champ now.

Laugh away.

Dont worry dude we all have had our moments, usually it's karma's way of schooling mechanics

It happens, I have pulled a few self inflicted mistakes myself. At least it wasn't a expensive fix and that is one thing that you wont ever do again. Sometimes those are the best way to learn. Congrats on getting it fixed and letting us know what it was. It might help the next guy out.

I am working on a 1992 pickup with the exact same problem. #1 and #3 do not fire #2 and #4 do. I have computer out and think I will get it tested. Any luck finding solution?

Yeah, mine was simple....I had the plug wires crossed on #2 and #4. I'd certainly check that you don't have the same problem.

I checked all plug wires they are right. I installed a header and a new cylinder head with an aftermarket cam. I am wondering if it may be an oxygen sensor.
