Massive problem with '93 Civic...
Ok, so a friend of mine's brother-in-law has a '93 Civic, and he was wanting a little advice. He was driving the car down the road, and it abruptly died. So far we've determined:
The car has no spark at the plugs or the distributor.
No reference voltage at the MAP or the TPS.
Fuel pump not getting any power, but if the main relay is manually grounded, fuel pump works.
No spark even when the main relay is manually grounded.
I'm leaning toward blaming the ECU, anyone here have any ideas?

Re: Massive problem with '93 Civic...
Could be the ignition relay AND main relay. Could also be a bad ignition coil along with a bad main relay. I would try checking all the relays before I purchased a new ECU.
No spark at the distributor could be the ignition coil.
No fuel pump could be the main relay.

No fuel pump could be the main relay.
