I have a 98 cavalier z24 that drove fine then It sat for about 4 days. Went to start it and it just cranks over but doesnt start. I hear the fuel pump come on so im thinking it may be an ignition problem. Also the car has gas in it. Any ideas on this would be appreciated.

The way I always rule out fuel problems is to remove breather and add fuel right into the intake . It will run although rough with the maf sytem it will defenitly rule out fuel problems pour in a few drops 1/2 oz. try starting stand back from intake

Or have somone feed fuel as you start it and be very cautiuos
