How can you test an ECU for a 1993 Civic ?

[QUOTE=Fosters80;299680]Its been a while since I had one of these, and I'm not able to get at my resources at the moment, but I seem to remember the 93 DX being prone to ECU failure. Try removing it and taking the cover off the ECU, there was a spot on the board that would be noticeably burnt. [QUOTE]

BTW , I love your project car. You do amazing work. Really looking forward to seeing that car on the road.

relays need 4 terminals.

fused power from the battery or a constant source.

ground.

trigger wire - comes on when ignition is on. Yellow and black pretty much all over the engine compartment.

load (to the fuel pump).

Sounds simple enough. I"m sure i'd manage to screw something to hell though.

If the replacement ECU doesn't fix things, I'll give this a shot.

I don't want to call it fixed just yet, but the replacement ECU plugged in and the car fired right up.

- in misty weather at that ( the main symptom before was that the car would not start when it was humid. )

Thanks everyone !
