03 chevy cavalier wont start

03-31-2013, 10:48 PM
have an issue drove the car outta town other day and had car towed home. had codes checked came out engine running too rich. i have changed oil, spark plugs, fuel filter, coil pack, ignition control module, intake air temp sensor. finally got the spark fixed but had standing gas in cylinders. So i got the cylinders all cleaned out from washed cylinder walls and put oil in to fix the compression issue ( it had no compression in all .cylinders). So at this time i have spark, compression, and fuel. when i checked last my exhaust was sucking in air. please help!!!!!

Just a guess.Plugged exhaust.or spark at the wrong time.

No, the timing is fixed.....it varies according to inputs to the PCM.....

So compression is well in excess of 100 psi?

I assume you changed oil due to the fuel in it.....

You have spark on all 4 cylinders?

You replaced plugs....used OEM and checked gap? Correctly hooked up wires in correct order?

If it doesn't start, then pull a plug and see if the plug is wet.....if it isn't, then try spraying carb cleaner into the intake...

Check for codes?
