SOURCE: Fuel pumps will not run!

Hey lets try this ! Locate your starter solenoid & look for a yellow wire marked with a "W" . That may be the fusible link for fuel pump. Let me know what you find.

SOURCE: I don't here the fuel pump ever kick on in my 1990 Ford F150, and I tested all of the fuses and they are good. I was thinking the relay for the fuel pump might be bad -- any suggestions?

It's under your hood, in one of those boxes, and should be marked. Your pump won't cut in if it's fried either. Check to see if there is power at the pump. Maybe you just have a loose wire. You can always hope!

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.

SOURCE: 1997 Ford F150 Electric Fuel Pump will npt pump

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 :

Where is the pcm located


Have you tried resetting the Inertia switch? This switch will cut off power to the fuel pump. It is usually behind one of the kick-panels. It is a safety switch and has a reset button on it. It can trip by mistake when you shut a door or make any impact motion. It is suppose to prevent gas fires in an accident.

Fuel relay on a 2002 f250 super duty, no manual



  • The fuel pump relay is in a junction box under the hood. The junction box you are looking for is the one closest of the two to the fender and of the three relays in there the relay closest to the fender is the fuel pump relay.

  • Also, here is a diagram of the fuel pump fuse. #40 - 20 Amp fuse.

  • Also make sure to check to see if the fuel pump shut off switch.

Truck will not start and i need to know where the fuel pump relay is located?


Your fuel pump relay is in the under the hood fuse box and should be marked. If not looking into the fuse box you"ll have two rows of fuses (side by side ) totaling 18 fuses, there are two relay just above the two rows of fuses and the one directly above the fuses is the fuel pump relay. Also you mite want to check your inertia switch and make sure the red center button is depressed ! you"ll find the inertia switch located behind the right hand kick panel (down on the floor inside the vehicle,passengers side ) good luck thanks for using fixya

1999 Ford f150 V8 4.6 Fuel pump does not run up. Where is the relay and or fuse? How do I check the pump?


Did you check the fuel inertia switch ?

From the owners manual pg 155 :
Engine compartment :
Fuse # 10 - Fuel Pump
Fuse # 18 - Fuel injectors

pg 156
Fuel pump relay relay #302
You can swap the fuel pump relay with one of the trailer tow adapter relays to test with.

You can always jumper the normally open contacts in the relay socket ( shown as the red line below ) :

Have a 96 ford f250,cannot get fuel to carburator,wheres fuel relay and how do i solve my problem


First you'll want to check all your fuses in the interior fuse panel and replace any that are questionable. the fuel pump relay is located under the hood, sometimes mounted on the firewall but usually located in the main fuse box under the hood. After checking the fuses, put your keys in the ignition and turn it to K>O>E>O. Key On Engine Off, and listen to see if you hear the in tank fuel pump start buzzing and then cut off. It doesn't stay on at that point, it's just pressuring up the fuel system preparing to start. It might take a couple of times until you hear it. If you don't hear anything at all, and your fuses are good, Your in tank fuel pump is the more likely the culprit. It's about due for one being that its 13 years old. Merry Christmas.

No power to fuel injectors


Determin if the injector operating:
  1. disconnect the injector electrical connector and measure the resistance of each injector with an ohmmeter. Compare the measurement with the resistance value Specifications are 11 to 18 ohms.
  2. Replace any injector whose resistance value does not fall within the specifications.
If the injector was not operating but the resistance reading was within specifications, the PCM Powertrain Control Module (PCM) or the circuit to the injector may be faulty.

Check the ignition fuse located in the engine compartment fuse center. Also. check the fuel pump relay.
Note: The fuel pump relay is located behind the radio in the center of the instrument panel.

If the relays are good and the fuel pump does not operate. check the fuel pump circuit. If the wiring and the connectors are
good, replace the fuel pump.

Do you have access to an amp clamp to check amps going to the glow plugs. Remove the oil temp sender which is on the back of the hi psi oil pump reservior 2 wires. This will make the relay run longer. Then hook clamp over the 2 brown wires on glowplug relay should have about 175 amps if its working right. I have also seen the fuel heater inside the fuel filter housing go bad as well. Might check all the fuses as well incase the fuel heater fuse is blown.
