hey guys i have a 01 chevy cavalier that does not start i have fuel i have spark i have compression i even removed the 02 sensor thinking not enough back pressure i have injector pulse eveything has anybody ever run into this problem its a 01 cavalier 2.2 engine single camthere is communication with pcm and scanner as ell any input would be greatly appriciated

 

If you have compression, a spark, fuel, and backpressure, it'll start assuming your starterworks and the battery is charged.

Have you checked the throttle body and PCV valve for blockages?

 

HOW ABOUT CORRECT TIMEING

 

Given the information you provided, I'd seriously lean toward the Crackshaft Position sensor.

 

i hooked up the scanner and the crank sensor seems to be working fine timing i havent checked that is my next step im going to start removing the timing cover tomorrow but if it as the crank sensor was bad oulnt i have no spark and i do have spark

 

I forgot to mention timing. Yes if youre sparking late, thats def. an issue.
