Reposting in hope of more replies... I've searched the web high and low, no one has a problem like this. Okay, 91 crx si, b18a1 out of 90 integra. Basic LS swap, nothing unusual, basically followed the online guides. Had the thing running perfectly, driving around fine for a few weeks, then all the sudden she died on me. Getting good fuel, good spark, compression in all cylinders. New timing belt, water pump, fuel pump, the works. Seems i've checked everything, still no start, tried new ecu, no-go. Main relay is good, timing is dead on. Something had to have gone wrong as I was running it, that's the thing that's got me confused. I think it has to be an electrical problem, anyone have an idea where to start? Or possibly other suggestions? Help please.
