SR20 won't start! Halp!

[guitardave06]

So I just bought an S13 with an SR. It was running fine and made the 140 roundtrip drive to work for almost a week, just fine. Well after getting back into town yesterday, it was running fine when I pulled into the car wash. After I washed it (self serve car wash), I started it and it began to run on only or 2 cylinders. I figured something just got wet so I turned it off and popped the hood to try and figure it out. I did everything I could with the resources that I had, then called one of my buddies because I couldn't figure it out. He messed with it a bit trying to figure out what was wrong by process of elimination. We eventually got it towed to a busy of our as shop. We liked at it tonight and tried/did a few different things. Switching out the ecu, changing spark plugs, checking the CAS, checking spark, regrounding the battery and motor, checked for fuel delivery, checked the ignitor/ignition but still no luck.


We are short of at a loss. Any help would be greatly appreciated guys!

what were the results of the spark test? Do all cylinders spark?

Do a compression test,
check the fuel pressure,
check for spark on all cylinders,

spark/fuel/air should cover it

[guitardave06]

Spark is good, as well as the fuel pressure. Haven't done a compression test yet, but we will probably check that when I get off of work. Would bad compression on one or more cylinders cause it not to start? When I blew rings on my KA-T it started but smoked really bad.

Bad compression in one cylinder will not cause the engine to not start it would have to be all cylinders or zero compression.
Sure there's probably a combo but either way you still wont start.

Spark, Timing, air, fuel and compression.
