Not yet. Kevin is replacing some IC chips in his ECM which I am waiting on his findings, and then I will probably do the same this week.

Everything I've done goes back to the ECM/ECU, the wiring harness seems to be o.k. and unless something else is affecting the ECM that I haven't found, then the ECM needs some work.

I'm not ready to dish out $1030 for a new one yet, if a handfull of $.80 chips and some carefull soldering will do the trick.

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.

wondering what the final outcome was on this
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. :)

Hope this helps..............although VERY late.

Kevin
