Check to make sure the Security light in dash on right hand corner is not on. If it is on , your passlock is enabled. to dissable it turn your key on but not start it and wait for apx 10-15 minutes. this should re-set it.

SOURCE: Fuel pump relay

GM relays don't reset. My guess would be the electric fuel is not operating, For openers , I would start with the FUSE for the fuel pump. In a fuse panel UNDER THE HOOD. Should be marked. Probably a 30-40A maxi fuse. CHECK WITH A 12 VOLT TEST LIGHT. If that area passes all the tests, I would check for power to the fuel pump ( with the ign key on. 12 volt test light will go ON then OFF ) Could be a faulty fuel pump, Hope this helps

Car wont start


My routine to check non-starting motors: (petrol/gas models)

  • Check immobilizer status
  • Check fuel supply -does it reach the fuel rail when starting. If not OK, check 12v supply to fuel pump when starting. If OK, fuel pump maybe dead.If not present, check fuel pump fuse and relay.
  • If fuel supply is OK, check spark ignition. If not OK, follow the supply circuit backwards to the ECM. Coils and/or ignition amplifier connector should have one 12v supply to it when ignition switch is on.
For Diesels with 'common rails' you can take same approach for fuel. No ignition testing possible. The diesel fuel pump still needs battery power. It will make some sound when IGN is on. If not, check ALL fuses and relays.

Ok lets start at the beginning.
You may need a repair book and test equipment to fix this.
First, are you getting power thru the PCM relay ? The relay provides power to the fuel pump relay and the computer among other things.
That relay and the fuses that protect it can affect both spark and fuel.

1999 olds alero---cranks strong but wont start---n gas needle goes to empty when turn key to on position


check fuel pressure.sound like fuel pump not working.fuel pressure should be 41 - 47 psi. if not replace fuel filter, still too low pump faulty, if you not getting fuel pressure, pump still not working check fuel pump fuse and relay.code scan car first look for fault in pcm.it controls the fuel pump relay and fuel pump.

Where is the fuel pump relay switch


I replaced the fuel pump and the fuel pump relay also the battery is new and its cranks but it is not starting. What do I need to do next? or replace? possibly since its a 2002 Alero, would it be the ignition switch?

99 olds alero; fuel pump and inst. panel isn't getting power


fuel shutoff switch is actually a fuel pump relay in the relay box under the hood, but it is not unusual for a fuel pump to work on and off before it finally dies. but it is a good idea to check the relay first.

try swapping it with the horn relay (if the horn works). pay attention to the direction the relay is in. on GM's, it's possible to put them in backward or even miss the connectors completely.

you also want to check for proper power and ground in the relay socket.
