Yes, check the fuse and relay to/for the fuel system. If its been awhile since the fuel filter has been changed, it could have taken out the fuel pump or the fuel pump just is worn out. But run some tests first so you don't waist your money. It could also be injectors, fuel regulator, coolant sensor, wiring, or a bad ground.

I believe the fuel pump is in the tank, all you have to do is have someone turn the key on but do not start and you should be able to hear the pump working for a few seconds,no sound the pump is bad,or could be the fuel pump relay

New filter new fuel pump won't stay running


Well your engine has a carb, so it could be dirt in the carb, or a vac leak, or several other possible causes.
Does the choke close when the engine is first started ? Have you checked the fuel line to see if the pump is providing gas ?

2002 Ford Explorer ran out of gas put gas in and won't restart. replaced fuel pump and fuel filter still won't start. Cranks but won't start


Most Fords have a fuel reset button. When you ran out of gas you tripped the circuit. Most of the time the button will be on the passenger side by the kick panel. The exact location should be in your owners manual or your local library or auto parts store will have a copy of one for your specific vehicle.

1987 mercrusier 180hp wont stay running unless i pump the gas


Could be a small amount of rust got into fuel filter from sitting empty, try changing fuel filter before worrying about the fuel pump.Filters could be partly plugged and its always smart to start with the cheaper fixes first.

6.6 diesel shut down after starting, still cranking strong but won't start.


I would double check to make sure no air was in line. If it still won't crank, has to be pump.

Sounds like fuel pump is bad. Running fuel low puts alot of strain on electric fuel pumps. The fuel acts as a coolant for the pump, that's why it's advisable to keep at least 1/2 tank. It sounds like your pump finally just gave up. Pump might be making noise but it could just be spinning and not pumping. Have someone test your fuel pressure to confirm.

The car was running fine we drove it to the grocery store and came out it would not start put gas in it and it started-got it home shut it off went to crank it and it would not start-added more gas to it...


Believe your fuel pump is bad when you first turn on your ignition (don't try to start car) do you hear a clicking or humming noise? If not you fuel pump may not be working also check fuel pump fuse and relay check owners manual for locations.

Honda passport ran out of gas. now won't start. Could be gas filter?Put 5 gals of gas in tank. Will start with gas added to air flter intake, but won't stay running


It's possible that you have an air bubble in the fuel line. This blocks fuel from reaching the engine. To clear it, you will have to bleed the line at the fuel filter.

The other possibility is that the fuel pump is not working. Turn the ignition key to the on position. You should be able to hear the fuel pump humming. If not, check the fuel pump fuse, in the fusebox under the hood. If the fuse is ok, you will need to trouble-shoot the pump.
