Question about 2002 Chevrolet Cavalier Coupe
Could be fuel pump or the fuel pump relay and only checking the supply to the pump during a no start episode is likely to provide a valuable clue.
Don't ignore the possibility of an immobiliser fault...

Try looking at the fuel filter, it might be partly clogged or just clogged.Locate the fuel filter, disconnect it and (I know this sounds strange) blow through it, if you get resistance of any kind, then it's bad, if it blows completely through with NO resistance at all, then it's good.

Okay there should be a plug on there make sure it is pluged in all the way. If you have someone to help you pull one of the spark plugs out plug it in to the wire (Do Not Hold Wire with Bear Hands) use insulated pliers.try to start car if you don't see a spark from plug then it means that the coil pack is bad. If it does spark then it is possible thet it may be a fuel problem.

What about the fuel filter????? Have you changed it out??? If you can spary something like a started fluid, that means it is a fuel problem. My last check, it has to be above 50-psi on the fuel pressure to make it run right. I had 35psi, but whould not get over 30mph or down hill maybe 45mph. Check both filter & pressure, but check pressure with a New fule filter!!!!

have you considered it possibly being a the catalytic converter? Once it has sat for several hours will it start again?

SOURCE: Hello. My 1997 Chevy Tahoe
Now you have a good battery & a starter that turns over the motor
Have you cycled the key on & off with a fuel pressure gauge on the
Do you have a fuel filter that isn't over 3 or 4 years old?
Have you checked for spark while cranking ? Use an old plug on the wires,
if you have ignition wires,don't ground the wire without resistance
If you removed the ducting & MAF Sensor it won't start
Tell us what you checked & exactly how that was done.

It sounds like your on the right track, the next step is to do a compression test to verify good rings in that particular cylinder.
