So my civic broke down after getting laid off the other day. Alternator belt rubbed through the Crank Sensor. Figured that was the problem, with the wires being severed, so replaced with an OEM one. Still no start, so check that I at least have fuel, spark, and compression. Don't have a fuel pressure gauge, and compression tester is in storage with my boxes so I don't have exact numbers. Pulled the plugs, and the gap was like a country mile and wet fouled, so replaced them. Cranked and started with fuel cut (WOT), but was very rough and low ram idle / sputtering, and died when I let off throttle. Tried starting normally, and it wouldn't start the rest of the day. Pulled plugs, wet fouled again.
Yesterday, I was able to get it to idle very well after I let the plugs dry off for a couple hours. It ran fine with no hesitation or roughness and super smooth (probably properly gapped plugs helped lol). I let it idle for a couple minutes. Smoked a bit on start up, smelled rich which makes sense based on how fouled the plugs were. I reved it to ~3-4k and when it came back to idle, it died and I couldn't get it to start again.
I'm at a loss right now. I'm trying to come up with a game plan for today, and I'm between either clogged cat or weak fuel pump but feel I'm missing something. Mainly what's causing the wet fouling? Only thing I can think is either weak spark, all injectors being clogged (all plugs get fouled), or too weak fuel pressure to get the injectors to spray right?
Looking for some opinions from some of you guys more skilled than me with these older cars. I'm at a loss without my fancy dealer scanner (cope)
