Question about 2003 Chevrolet Cavalier

1 Answer

My 2003 Chevy cavalier was running fine this morning and now it wont start. I am thinking the fuel pump has went out on it but I have pulled the relay from the AC and swithed them around but still nothing. How can I find out for sure if it's the fuel pump or not? Or could it be something electrical?

With a test light probe...Check for voltage signal at the fuel tank harness connector unplugged and probing the connector cavity.Key ON/no start cycle will power the pink/blackwire for 3 seconds (10 secs apart) each attempt. If the test probe illuminates each key cycle,it gives you an accurate diagnostic for your symptom and you can proceed with fuel pump replacement knowing it is the failed part.

2003 chevy cavalier fuel pump will not kick on and the fuel pump is fine did replace the relay switch and still want start.


how do you know the fuel pump is fine. did you check for voltage at the pump. When you cycle the key you should have a reading for 3 seconds, then it should drop to zero. You only get a steady voltage if the engine is running. If you spary quick start or brake cleaner in the throttle body and it starts you will need check the above suggestion.. If you have a 3 second pulse then the pump failed

check and see if you are getting fuel at the fuel rail. the is a technical service bulletin for no start concerning the fuel strainer. the 03 came with a 100 micron strainer which clogs causing a no start problem due to low fuel pressure. should be 40to50 psi.
you can try tapping the fuel tank with a rubber mallet sometime that will getting the fuel pump working temporalily. also check the ignition module on top of the coil packs this part controls the spark. hope this helps

check to see if you can hear the fuel pump running.just cycle the key to the on position but dont turn over the motor you should hear a humming sound come from the fuel tank.if no sound check your fuses if all ok could be a bad fuel pump
or check to see if you have spark if no spak then it could be the module inside your distributor cap.it also controls the fuel pump.
