Are you hearing the pump run when you turn the key to ON? If not, you may need to reset the emergency fuel shutoff button. OR it might be a fuse or relay .
If you hear it run,it should prime right away. don-ohio (:^)

Why the fuel pump don't run and the relay don't click when i turn the key on?


If you can't hear your fuel pump priming then either, the pump needs replacing or the relay. If you replace the relay and you still don't hear the pump prime then it's the fuel pump.

Car ran out of gas and has been hard to crank every since. I don't hear the fuel pump prime but I do hear the relay click. There is no gas expelled or pressure coming from schrader valve and also batt


the fuel pump is burnt out. the pump uses the fuel to cool itself. running low fuel the pump heats up and burns the plastic gears inside. thats why the fuse blew. need to take out gas tank to change pump.

2001 honda passport not getting fuel


First off, do you hear the fuel pump priming when you turn on the key. Should hear a light buzzing from the fuel tank for approx. 5 seconds. Have you opened the pressure line or the pressure test port on the fuel line on top of the engine to see if you are getting any fuel even trickling out especially during the priming. Pressure should be in the neighborhood of 45-50 psi for the system. A fuel pump can slowly fail, by losing pressure, but still can move some fuel if you hear it running oon the prime cycle. You can often borrow a fuel pressure guage from your local chain auto parts store to actually see what's goin on with the fuel system. You hook it up to the test port on the fuel rail and watch the pressure on the prime cycle. If it is very low, try priming the system 3 or 4 times to see if pressure builds, if not that would lead to testing the pressure regulator. But that's for next time.

No fuel up to injecter pump truck just stalled


Did you check for fuel pressure on the line from the tank while you had the filter off? Do you hear your fuel pump prime when you turn the ignition on? First I would listen for the hum of the fuel pump when you turn the key to the run position (not starting the engine) May have to get a helper and listen at the gas filler neck with the cap off. If you dont hear your fuel pump, check your fuses and relays. If the relay clicks when your helper turns the key on ( put your finger on the relay and ear down close to feel/hear the relay actuate)., and fuse is good, yet you do not hear the pump prime, I would say your fuel pump is shot.

If it is a diesel,check for fuel pressure coming off the direct drive pump hose while cranking the motor.

Wont start unless manually primed


Turn the ignition key to the ON position without starting the engine

You should hear the fuel pump priming for about a few seconds then shutting itself off.
If not hear replace the engine oil pressure switch
The 3rd wire to that switch is the pumps prime switch lead.
When the engines oil pressure is reached the computer will shut that circuit off and turn on the fuel pump relay
If you hear the pump prime the relay maybe at fault instead

Ok in order to pour gas in what i called the "carb" i have to take some sort of breather off. i have a 2000 chevy blazer 2wd cyl vortech is it the fuel pump gone bad or could it just be out of...


turn key on and listen for fuel pump in the tank, it should go on for a few seconds then turn off. if you cant hear it try to listen at the fill cap when someone else turns the key on. if you cant hear it , check the safety shutdown relay under hood, it shuts down fuel pump and ignition

No fuel getting to fuel rail.


fuel pressure regulator is what is in between the pump and the rails. it sounds like your regulator is restricting fuel flow
