Ecu Problems/wiring Problems

[awdcyclone]

from previous problems, i found out that i wasnt getting spark in cyl 2 or 3, so i replaced the coil pack, no the only problem is that it dosent seem like im getting fuel to cyl 2 or 3, i did the test on taking the injector wires off and only 1and 4 started making the engine run bad and 2 and 3 stayed made the engine run normal, i was wondering if the ecu would cause that or could it even possibly be wiring.

I am going to guess ecu. I had similar problems awhile ago and replaced the capacitors on the ecu and it cleared up for one day. But now I have new problems.

I'm having the ecu bad dream at this time also, chattering ecu relays & stalling. I replaced the caps & the problem remains-before I get into the details too deep, I emailed Tom Stangl today to inquire about having him check/repair my ecu & he said the problem might be in the ecu power relay. (earlier in the threads was mention of someone installing a known good ecu into his car & still getting the chatter/stalling-which also sounds like a case of bad ecu power relay). So far in my search, I have not been able to locate where this relay is, does anybody know? It sounds like the right thing to do is check this relay before tearing into the ecu, but of course that's not how I did it because I was following the advice in the 1000FAQ.
Where is the ecu power relay?
