Thanks Duder for the update, got almost the same problem as you... only getting spark on 2 cylinders on a '94gt (wish it was a vr4)
Most posts I read said the ECU/ECMs CAPs were not a problem on a 1994 gt so I'm thinking it's got to be something else.
Going to make a new thread for my car... if anyone post something besides the ECM that works, i'll get back to you.
Can't believe it's been almost 20 years.......and that I didn't respond with my solution.
My problem ended up being the ECU after all.
The failed/leaked capacitors had corroded the circuit board trace leading to small vertical circuit board(that generates the firing signal to cylinders 3 and 6). Surface mounted IC's, on the small board, were damaged as a result of the trace corrosion.
I repaired the corroded trace, and replaced the damaged IC's.
The ECU is still in the car.....................but.......I still bought a "spare" ECU.
