2005 Chevy Cavalier Fuel Pump Shut Off. Then it would crank up just fine later. First check for spark at any of the sparkplugs if you have spark then check your fuel pressureJust because its working doesnt mean it has enough pressure for it to runIt may be a weak pump.
Having intermittent problems with the fuel pump. Then it would crank up just fine later. Remember that there is also the switch that will prevent the fuel pump from running unless your engine has oil pressure.
It was really hard LOL to drive around and it wasted a lot of gas to try to keep it pumping gas.
Siphon the gas tank. The pump should come on for a few seconds and then shut off if the car fails to start. Mcberta1 this car has an electric fuel pump protected by a fuse and switched by a relay. Having intermittent problems with the fuel pump.
