I purchased a 1998 Sunfire 2.4L w/ 117k Autom. All it needed was a good cleaning to be presentable. Everythging was fine until my son degreased the engine. Now there's intermittent problems.
Sometimes the car starts fine. It's completly normal. That seems to last for what seems to be the next 3 , or so starts, then it goes into antitheft mode. It starts, then stalls. I do the passlock clearing proceedure (leave the key on the on possistion for 10 min.) this does work and allows the car to start. However, after it starts, about 2 sec. later, there's a clicking noise from the instrument cluster as the (oil, alt, coolent, antitheft and check. engine) lights blink a few times, then stay on. The RPM gauge also clicks and bounces up and down too, then goes flat. The car runs just fine. I can shut it off and it will restart multipal times. However the same thing continues to happen w/ the dash lights and RPM gauge.
Then I re-do the passlock clearing proceedure again and then the car starts as normal, no clicking noise or dash lights on. Again this might stay normal for the nxt 3 - 5 starts, then it all repeats itself again
Anyone have ANY ideas as to what might be causing this, or as to any possible fixes.
Thanks , in advance, for your consideration, time and efforts.

You most likely got the ECM (electronic control module) wet. These are notorious for this, as they are in the worst spot ever. Behind the front right fender (pass. side) on the inner wheel well. between the tire and front bumper. This will cause exactly what you discribe. There was a recall on these Sunfires, to put a protective housing over the ECM. You should check to see if your cars been recalled. (Call a GM dealer,you'll need your VIN #) This could take days to dry out, maybe longer. before things return to normal.
