Willnot turn over.battery good and at 100%.fuel pump kicks on and relays by fuse panel click when trying to stat

many reasons but start with these check and test fuses relays -fuel pump --fuel filter --ignition

Power For Engine Control Relay ( fuel pump) Comes From Fuse Link 2 (20 Amp) Behind Battery--Engine Control Relay Is Located Below Right Side Of Dash--At Kick Panel--Output To Fuel Pump Wire Color Is BLACK/BLUE

check all your rounds on the body, behind kick panels, and in engine compartment. The relays you hear clicking are the power relay whcih turns your engine computer on. The other relay is the fuel pump relay, which is turned on by the engine computer. start there, report back.

PS. When you press the gas pedal to the floor during cranking, it shuts off the fuel supply to clear a flooded engine.

It is located in the relay and Maxi fuse box under the hood near the battery, both the fuel pump fuse and relay are in this box, the fuel pump fuse is a 20Amp and is marked #10, the fuel pump relay is is marked as relay #301.

There is also a fuel pump cutoff switch (triggered by an accident exceeding 3 G's)

The fuel pump shut-off switch is

located in the passenger's foot well,
by the kick panel.

Hello,

In your power distribution box in your engine compartment (Ford recommends

disconnecting your battery before servicing fuses / relays in PD BOX )

fuse # 9 - 20 amp mini-fuse for fuel pump relay and RAP module

relay # 5 - is the fuel pump relay in your PD BOX

also , the fuel pump inertia (shut off) switch is in the right front passengers

footwell by the right front kick panel.

Thanks..

Thanks for choosing FixYa and welcome to the site. When you first turn the key, you should be able to hear the fuel pump kick on. You should hear a buzzing sound for a second or two. It may be the fuel pump, clogged filter, bad injectors, fuel pump fuse, relay, or reset, if equipped. It could be in the ignitions. Let me know if the pump is kicking on and we will take it from there. If it is not, check to see if it is the fuel pump fuse or relay. I am not sure which ones you have. It should be marked in the fuse box though.

Once you check the fuel inertia switch in the passenger's side kick panel, next is to check the fuel pump fuse, engine compartment fuse # 10.

If this checks OK ( power on both sides ), you can pull the fuel pump relay, and jumper it.

The engine compartment fuse panel is where the fuel pump relay is located at ( relay # 301 ). Pull the fuse pump relay out of the socket, and using the diagram below, with the red line, momentarily jumper the Normally open contacts, you shoud hear the fuel pump run. ( mind the pin orientation when doing this ) :


I had a bad fuel pump relay on my 2001 F-150 @ ~ 36K miles. Replaced with the trailer tow battery charge relay ( relay #302 next to it ) and it worked again.
The symptom I had was a crank no start ( theft light on dash went out ).

If the fuel pump does not run, and power is on pin #30 in the relay socket, next is to check the output of the fuel inertia switch in the passenger side kick panel. The output of this is the Pink w/ Black stripe wire. The connector to the fuel pump inertia switch should be a 2 pin connector, the other color in the connector is Dark green w/ Yellow stripe wire ( that is from the pin #87 in the relay socket in the engine compartment ).

If that circuit has power at the passenger side kick panel, next is to check for power at the fuel pump at the fuel tank. The fuel pump motor is the same Pink w/ Black stripe wire. The connector is a 4 pin connector with black ( ground for the fuel pump ) black w/ orange stripe ( ground for the fuel level ) and yellow w/ white stripe ( to the instrument cluster for the fuel gauge ).
When testing by the fuel tank, make sure you have a good ground for the meter ( extension from neg on the battery or trailer tow adapter ) as that could also be a problem under the truck.

Sorry for war and peace, hope it helps.

When you are trying to start the truck, does the theft light on the dash flash rapidly ?
- This would be a problem with the key used, PATS is not recognizing it as a programmed key, try another key
- Could be a problem with the PATS transceiver if 2nd programmed key does the same thing, wait on confirm to get into this, kind of long.

Have you checked the Fuel Inertia switch in the passenger side kick panel ( button reached from the top, needs to be pressed down ) ?

When you turn the key from off to run ( do not start ) do you hear the fuse pump run for ~ 2 seconds ? Should be able to verify at the schrader valve at the fuse rail for pressure ( safety glasses and a rag )
- Fuel pump fuse is one to check, Engine compartment fuse panel, fuse # 10 & Fuse # 18
- Fuel pump relay could be a problem, can swap with a trailer tow relay from the battery charge function ( if the trailer tow package is installed ).
- If both of these are no change, turn the truck to the run position ( do not start ) and hit the bottom of the fuel tank with a rubber mallet. Could be the fuel pump is plugged or on its way out.

Other item to check, is the last time the fuel filter way changed.

Check the fuel pump fuse and relay under the hood in the fuse panel. If both fuse and relay are good then fuel pump may be at fault, but it seems too new for a fuel pump replacement. Hope this helps. Keep me posted please. Good luck
