Trying to locate fuel pump relay location on the fuse panel under the passenger side dash. I changed the fuel pump and the truck is still running rough. I changed the fuel filter as well. The roughness is at idle and the truck runs semi well after the initial take off.

You have to take off the passenger side knee bolster for the relay. From the trans tunnel to the door- Fog lamp relay-Courtesy Lamp Relay----Fuel Pump #1 Relay-Horn Relay-Rear Defogger Relay. Fuse is located in the Main Fuse Block Located on the right side of the dash (small panel pops off the far right side) passenger door needs to be open to do this. The fuse is labeled FP 1 and is the furthest fuse left on the second row from the bottom Red 10 amp. Fuel pump is located under the fuel door in the back of the car- you just need to take the door off and you can check for voltages or even replace the pump from there- no need to drop the tank or anything .

fuel pump fuse is located under the dash on the driver's side. Look for THIS -



The fuel pump relay is located underneath the dash, driver's side, up behind the metal panel (behind the plastic kick panel). It is NOT plugged into the fuse panel.




See #18 in this diagram -

most fuel pump relays are located in the main fuse box,under the hood. look for a black box on the drivers side,or passenger side fenderwell under the hood. lift cover off and look on underside of the fuse box lid for location of the fuel pump relay and main engine fuse.hope this helps and thank you for choosing fixya.com

The fuel pump fuse located under the hood, behind the passenger side headlight. There SHOULD be a bank of 2-8 relays, with some fuses. One of those fuses (in a plastic protection carrier) is for the fuel pump. Its under the hood,passenger side, front of engine, passenger side of radiator,mounted on the relay panel(4or5 boxs)look for a long black thing and pull down on it,a #15 fuse.----------`- Thanks.

Hi!!

Check for a 15A Fuse labeled FUEL PUMP on the cabin Fuse Box located in the front seating area, driver side, under dash, behind kick panel.

The diagram shows the Main PCM relay controlling the Fuel Pump, but it wont hurt to check the cabin fuse box under hood, passenger side, rear side of strut tower, mounted in fuse/relay box on firewall
Don't forget to rate this post, Good Luck!!!

there are many placed located but the rarely are under the dash on the passenger side , first you need to be sure if the ecu is ok than you need to be sure all fuse are ok and need to check up the pipe into the fuel pump are fitted correctly

The fuel pump relay (square/silver looking part) is located right above the fuse box panel under the driver's side dash. Go under the driver's side and you will see two squares. It'll be the one that is higher up

there are two fuse locations, under the dash by your left foot, and under the hood behind the passenger side headlight.

Your question is really NOT that easy to answer, there is no stock location for a "fuel pump relay" fuse, the fuel pump is powered by power coming from the MFI relay.

Fuse #1 under the hood supports the MFI relay as do fuses 1 and 12 under the dash. Check all three.

There are reasons a fuel pump won't start that are not related to the fuse... if you check them and determine that the fuses are not blown, with the ignition turned to the on position, try powering the fuel pump test jack, if your fuel pump comes on, it is something else (probably a bad cam/crank sensor)

To power the test jack, run a test wire from the positive terminal of the battery to the connector stuffed down behind the passenger side strut tower between the strut tower and the fire wall. It should be a black connector connected to a single black wire with a BLUE stripe. There will be three connectors bundled together, a black one, a blue one, and a round brown one (the round one is for setting timing and the blue is for setting idle, do NOT mess with them)

When you power the test connector, the fuel pump should come on, regardless of the MFI relay or the fuses... if it does not, you need a new fuel pump.

There is a Fuel Pump relay. Not sure if Ford has a Relay Box under the Hood though. There are also Fuses that Control some items of the Fuel System. Try the Relays first and see what you have.
