If the car has been in a collision, some have a centrifugal switch which will cut off the power to the fuel pump. Typically this is located on the interior of the car behind a panel, sometimes in the door jambs. Even if there hasn't been a collision, it's worthwhile to see if you can find this switch and determine if it's been tripped. It works like a circuit breaker, you just press the button back in the reset.

If this isn't the case (or if your car doesn't have a shutoff switch), then your problem could be the fuel pump relay. Check your fuse panel to see if there's a diagram that gives you the location of the relay, then see if when you jump the relay if the fuel pump goes on (have a helper stand by the tank to see if they can hear it buzz). If it goes on my being jumped, get a new relay.

Hope this helps.

Fuel shut off switch location on a 74 alfa romeo spider 200

Does the fuel pump run? The inertia switch, if tripped will prevent the fuel pump from running. If the pump runs but the car doesn't start than it's likely a problem with the fuel pressure regulator or the bypass internal to the pump.

Where is the toggle button on my 2002 taurus? I can't find it and the dealer says I need to reset it for my car to start.

It is called the fuel pump reset switch, it is not a toggle switch it is a resettable spring loaded pop up switch, the location is shown in the owners manual under fuel pump reset switch. in the index.

Will not start up fuel was low fuel relay /pump

Reset the electronic fuel pump there are instructions on this procedure under the hood on the radiator support. it says if vehicle does not start..... Just follow instructions and it should work.

After a collision, if the engine cranks but does not start, the fuel pump
shut-off switch may have been activated. The "Fuel Reset" indicator light
will illuminate in the instrument cluster. The shut-off switch is a device
intended to stop the electric fuel pump when your vehicle has been
involved in a substantial jolt.
1. Turn the ignition to the OFF position.
2. Check the fuel system for leaks.
3. If no fuel leak is apparent, reset the fuel pump shut-off switch by
pushing in the reset button.
4. Turn the ignition to the ON position. Pause for a few seconds and
return the key to the OFF position.
5. Make a further check for leaks in the fuel system.
Roadside emergencies
The fuel pump shut-off switch is
located in the passenger's foot well,
behind the kick panel.

2000 Crown Vic cranks but won't start.

Check the fuel pump reset switch again, if it is popped back out then replace that little switch in the trunk, any ford one will do. it works off a magnet and a bearing to close the circuit for the fuel pump. easy fix.

Hi, back again. Changed the fuel filter and a new

No fuel pump reset switch on a Jimmy. If your pressure goes up to normal, then drops back down after 2 seconds, you need a new fuel pump as the return is not working correctly to keep fuel in the lines.

1999 lincoln fuel pump

My fuel pump on my 1998 Lincoln Continental has no power. I checked the fuse it is good. I checked the fuel shutoff switch it was fine. I have traced the wire from the fuel shutoff switch to the fuel module driver in the trunk. The wire has power. I have also traced the positve wire from the fuel pump to the fuel driver on a different terminal, this wire has no power from the pump. I also changed the fuel driver, the low fuel pressure switch, the alternator, and battery.does anyone have any suggestion's?
