Sorry- forgot to add the other stuff!
The ECM- that'* the one under the hood, correct? Not the one inside? I'll try to find it, but what years are compatable? Just the 94s and 95s? I might have a friend with one that I can at least swap out to see if that'* the problem.
Thank you guys so much for helping a guy out on here- I'm quite sure you all are so much more thorough and exact than the joe-schmo at a big garage. Not to mention so much easier on my already thin wallet!! Haha
Thanks folks-
Justin

This write up has a bit at the end about testing plug wires.

Cool, thanks! I'll check the cables tomorrow. Until then- is the ECM the same as the ICM? I couldn't find anyone that had an ECM, but a couple guys have an ICM. This is the one under the coils, right?

ICM is Ignition Control Module. Yes, that'* under the coils. ECM would be Engine Control Module. That'* the computer that runs it all. Also called a PCM.

Ok- so. I'm going to punch my car. I have a friend with a 95 too, so I swapped computers, no change. Tried the tps, no change. Checking the fuel pressure at the test valve would show a bad regulator, too, right? With good pressure, could we rule out the entire fuel rail as being acceptable? Is there a way to check just the pressure regulator?
Thanks for keeping me goin guys....
