I have a 1995 ford f150 302 eddie bauer i tested the fuel pump in the front tank and it has power when i connected jumper cables to the black and red wires on it so i know the pump is good i also replaced the fuel pump relay switch. I turned the key on and still i cant hear ther fuel pump engage
Have you checked to see if your inertia switch needs reset? its located in the back of the vehicle and shuts off the fuel pump when in an accident or roll-over... i have found some that set over nothing. just push down on the red button and it will reset. hope this helps...
It fuel pump is bad or you have a short somewhere in the ignition

SOURCE: rear, fuel pump failed, so i switched to the front
sounds like a bad ground or short to the signal wire what you can do is trace the wires from the tank to the bulk head connector to check for brakes in the wire but first do a ohm test on the three wires with the key off there is resistance between the wire you have a short if not check for brake or corroded connections
SOURCE: no power at fuel pump or crash switch
OK, you may have a dedicated pump for each tank, if so; DOES THE OTHER TANK WORK? If so, you have a problem with the switching system or second tank pump. You may have been testing the electrical, but remember: even a pump that works does not pump gas of there is a broken rubber feeder hose inside the tank. I would consider dropping the tank taht does not work and checking the pump and filter inside. Make sure key is on and test (usually the gray wire). Good luck.
SOURCE: 91 ford ranger...fuel pump will not run pump is good
It won't hurt to jump sire to drive, It is designed to pump all time when the engine is running. The only problem is the pump should not be on if engine is not running since it is designed that way to prevent a fire while pump continues on once engine is stops in a car accident. There is a control device to immobilize the fuel pump, if there is no speed sensor signal from the crankshaft. This needs to be located and fixed.

Did you check the fuel inertia switch in the passenger side kick panel ?
The fuel pump is powered :
the fuse to the fuel pump relay.
The fuel pump relay to the fuel inertia switch
The fuel inertia switch to the fuel pump itself.
At the fuel inertia switch in the kick panel, power from the relay is the Dark Green w/ Yellow stripe wire and the pink w/ black stripe wire is the power. from the fuel inertia switch to the fuel pump.
If you jumper the fuel pump relay, you should hear it run. If not pull the fuel pump relay, and check the pins in the relay socket, pin 30 should be the power from the fuse.
If you have power at pin #30, jumper the relay socket as shown with the red line above, and check the dark green w/ yellow stripe wire at the fuel inertia switch for power.
Press the button on the top of the fuel inertia switch, and check for power leaving the fuel inertia switch on the pink w/ black stripe wire.
This is tests good, check for power at the fuel pump, same pink w/ black stripe wire.
Fuel inertia switch info is in the owners manual, If you did not get an owners manual with your truck ( purchased used ), you can download one from Ford :
