No spark on a 1g

[92nolatist]

Hey guys, so here's the thing; I washed down my engine bay this afternoon to get it cleaned up a bit. I started it up to leave and saw my a/f gauge was pinned on rich at idle( it went down slowly) and while driving home I noticed that my a/f gauge was not working at all. However it boosted fine and drove fine, but it stalled and started up again on its own only once while I was creeping through traffic. Pulled into a gas station, filled up and started it again to go home. Now a couple hours later, it wont start at all. I checked for fuel and its there but it has no spark. I think that some water got into some of the connectors so I dried them off and sprayed contact cleaner into all the ones I could easily find. Still nothing; I really need your help guys.

Thanks in advance,

Edit: OH, I forgot to mention that i recently swapped a 91 vr4 eprom ecu in to my car (nothing is wrong with it). And i did plugs and wires about a month ago.

Sounds like your cas.

+1 they are super sensitive. Either that or the power transistor pack. I would assume CAS as the first culprit

you didn't have problems till you washed the engine? than it probably has water or moisture inside the cas, or it has just quit working.

Hey thanks for answering me guys.

Ilco187---no I didn't have any problems whatsoeveruntil i washed the engine.

I was thinking the same thing but heres the weird part, with the key on, i disconnected the wire on the CAS then reconnected it again and my IAC buzzed and the Injectors clicked a few times. So I wasn't too sure what to think about that. Any ideas?????

Just a quick update--- my car started on sunday night without me having to replace anything. The CAS was soaked inside and i cleaned and dried it out. Everthing works beautifully again. Thank you everybody.
