    The reason why I don't hear the fuel pump when the ignition only is on, is because the fuel pump isn't an electric fuel

SOURCE: Fuel Pump Relay

Obviously, you can jump the relay but it is dangerous on an extended basis. You'd have pressure in the lines when you don't want it there. Replace the relay if it is defective.

If you have other issues, you can check the pump back to the tank by going on the business end of the relay and looking for resistance at the pump to ground. If it is open, the pump or the harness is bad...GMs have harness issues...not Fords.

SOURCE: solenoid was bad replaced it

Check the fuel pump cut off switch located behind the carpet on the passenger side up unde the heater box, pull the carpet back and see if the button on top of the switch is pressed down, if not there behind the panel passenger footwell right side same thing also make sure the switch has power coming in and going out. BUT! you gotta be quick the fuel pump relay controls this power and only suppllies power for 2-3 seconds then it turns off. so plan ahead get your test equipment all set-up and surn the ignition on if you have power great turn off the key and move test stuff to tho other wire on the fuel shut off switch get ready and turn on the key power good no power bad fuel pump switch but No power to the switch likely a bad ffuel pump relay.

How do you check the electrical wiring to the pump and if it is that is it something I can do? I have checked the fuel relay fuse and the safety cut-off switch and replaced the fuel pump and filter

It's a 2007 Chevy Malibu LS can it be the fuel pump cost it not to crank or start


Bad fuel pump will not cause it not to crank, but can cause it not to start. Test with fuel pressure gauge. If it will not crank, entirely different issue=bad solenoid/starter, bad battery connections, bad ignition switch, relay,wiring.

When i turn the key the engine cranks over but does not start, if i continue to crank it for a minute or two then it will eventually start and drive just fine. any ideas?


This sounds like a fuel system priming issue. When you first turn the key to the ON position (not cranking yet), you should hear a three-to-five second buzzing noise. This is the fuel pump running to pressurize the fuel system for cranking. This is controlled by the PCM and is relay activated. Once the vehicle starts and oil pressure rises, then the fuel pump is activated by the PCM via a different relay. If you can't start at first, what is probably happening is that the prime is not occurring and you have to crank it until the PCM sees oil pressure and then fires off the fuel pump. It could be PCM wiring or a bad fuel pump prime relay.

I have a 1999 Pontiac Grand Am why won't my car start? it just spins but wont crank. I changed the core packs and it's still not cranking


The term " CRANK" is what the Starter is doing to the Engine. I think you mean is 'it Cranks but wont Start'.
Is the engine getting Spark? Is the engine getting fuel? You need to check these two things before randomly swapping out parts.
If it's fuel starvation.. Check the fuel pump relay or possibly a bad Fuel Pump.

Where is the main fuel relay located


Stand by the gas tank while someone turns the key to ON. Listen for the fuel pump to come on for a second or two as it should. It will only come on for about two seconds to pressurize the fuel system, then shut off and only come on again when the engine is cranked. If you hear it, then the pump is working. Hence, you would smell gas after cranking the car a bit. If no sound from the pump, look for the relay in the power distribution box under the hood. The box's cover should have a diagram for fuel pump location. Or your owner's manual might show it.

1999 Ford Explorer Sport Starting Issue


It sounds like the pump is failing. That or sometimes not getting electricity. To check which it is, you could use a voltmeter or test light at the gas tank's electrical plug in. You need to check for power on the fuel pump wire when the engine is being cranked for starting. Do this when turning the key to on does not cause the pump to turn on for 2 seconds as it should. The fuel pump has power for those 2 seconds when key is turned to on, and again has power when the engine is cranked. You might miss the two second signal, so check for power when car won't start-when pump won't turn on-and with the engine cranking. If you have a signal then and still no pump coming on, then you must have a failing pump.
But if you have NO power to fuel pump wire with engine cranking, then it is a problem elsewhere-probably the pump relay (try a new relay if you haven't already). That relay is signaled by the engine computer when key is turned to on or when engine cranks . so you could do some testing at the relay if needed.

2003 Galant fuel pump ground problem


Power to the pump is provided by the relay for the first 3 or 5 seconds to build pressure back up to start. Once the 5 seconds are past, the relay is grounded by the computer IF it sees oil pressure or crank signals. This helps prevent a fire if the car is in a wreck.
If it still won't start with the pump relay bypassed, you would check for spark and see if the computer is getting a crank signal.

A friend of mine has an 89 grand prix turbo,the car sat for about 2 years and we're trying to get it started. we seem to think that the car isnt getting fuel, we checked the relay and swapped it out...


That is a good starting place; the fuel pump and filter. Due to the car sitting up, gas drys up or some times get thicker. Causing a once good pump to go bad.

Just changed plugs on 1994 ford explorer and it wont turn over wondering if its the gas ladder or fuel relay switch


Is it not turning over or not firing? If not firing, it could be bad crank sensor, coilpacks, or module
If no spark

If no fuel, bad fuel pump relay, plugged fuel filter, or low fuel pressure.

I started it up one day I went in to let it warm up came back out and it had died on me.Now it turns over but won't start seems like it might not be getting gas wwhat do you think?


first of all when you crank the truck have someone to smell under the hood to see if you smell gas if you don't smell gas then check the fuel pump relay before you do this get a can of starter fluid and spray it in the throttle body and if it starts then the relay is good then the fuel pump is bad
