There may be a problem whit your ecm (computer) or a bad contact on a fuse or the relay
the power your are getting from those wires my be the power for the fuel level sensor
when your turn the key on the run position you should have power for only 5 seconds
that is the computer activating the relay then it wont give power on till you crank the truck.
check for power on the relay contacts
you should have constant power on one terminal and you sud have power on another one for only 5 seconds when you turn the key.

Note is a good idea to change your fuel filter wile you are at it
if you have a clog fuel filter can cause your fuel pump to go bad.

2000 Pontiac Grand am Replaced fuel pump today. Nothing no fuel pressure when I crank it. I check volts at the fuel pump plug in I get 4.9 volts. Shouldn't it be 12 volts. Can someone answer this.


yes. It should be 12 volts. Did you use the replacement harness you should have gotten with the pump? GM has an issue with the harness going bad at the pump that's why new pumps come with a new harness. Also check the relay.

It seems i am not getting any power to fuel pump, replaced pump still no power dont hear pump turn on at key on position check relays but not sure on good or not


Replace the oil pressure switch for the third wire on that sends 12 volts to the fuel pump upon turning the ignition key on to prime. Once oil pressure is achived the computer shuts that circuit off and turns on the fuel pump relay to power the pump till you shut off the engine

I dropped the fuel tank to drain old gas.I put new gas in and turned engine to start it didnt start. Should I be able to hear fuel pump if it is working?This is for a 1990 ford e-150 van.Also where the is...


Turn the key to the ON position without starting the engine. You should hear the fuel pump running for 5 seconds if working. This primes the gas to the injectors when doing this. If not heard running check the oil pressure switch for the 12 volts needed to run the fuel pump starts there on that harness. When the engine starts and the oil pressure reaches the normal pressure the computer shuts off that circuit and turns on the fuel pump relay to run the pump. The relay stays on till you shut the engine off

Check for 12 volts power at the fuel pump harness. If no power is going to the pump, check the fuel pump relay. Also, check the fuel pump inertia switch. Ford usually has it on either inside left or right rear trunk fenders.

the computer is what sends the signal to the fuel pump relay. Check the harness plug at the fuel pump again they tend to get loose. there is an updated replacement plug for this. also make sure the terminals on the fuel pump relay are clean and not corroded.

1999 oldsmobile silhouette van won't start. no power to fuel pump


I have a silhouette and it had the same problem
Follow the fuel pump wiring harness to where it plugs into the floor of the van--pull the connectors apart--they will probably be corroded, and you will possibly have to change both wiring harnesses or connectors.

On my 1994 plymouth voyager the 3 wire harness to fuel pump (blue wire) doesn't have 12 volts; should it? fuel pump quit then worked once when hot-wired with 12 volts. fuse and relay is good.


The wire should not be hot until the relay is triggered. The relay does not get triggered until the ignition key is turned on. It will run for 3-5 seconds or until the system pressure it at max.

Fuel pump system


There is power at the fuel pump for aprox 3 seconds as soon as the ignition switch is turned on
then it does not get power again until the engine starts

so if you are checking the power at the pump you need to have someone else in the car to turn on the switch while you are looking at your meter , you have a relay under the hood under a plastic cover at the fire wall that controls the power to the pump .
