Ford Super Duty (1999-2016) :: F550 V10 - Fuel Pump Relay Location
I am looking for the location of the fuel pump relay for my 1999 Ford F550 V10 4WD Gas truck.
I have replaced the fuel filter and fuel pump. When the key is turned the pump gets juice and 2 seconds later is not getting juice. No lines are coming into it, so it's not getting up to pressure and shutting off.

I am trying to diagnose my fuel system, but I cant seem to find the fuel pump relay. My truck is an 2004 f250 crew cab work truck with 5.4L. it seems that the relay can be mounted anywhere from behind the radio or in the engine compartment as well as built in to the fuse box under the steering wheel.

1999 f-250 super duty... okay, here is what i have going on. basically no power to the fuel pump. For the last 2 weeks the fuel pump relay and 1 of the relays behind the radio (next to the blue relay) would chatter and the truck would die. Wait about 5 minutes and turn the key on and if the chatter was gone then it would fire up and run... So NOW no chatter on either relay and not cranking up. - motor turns over just fine- just no power to fuel pump. So I changed out the relay- both behind the radio and the one under the hood. still chatters and no start. i have checked the Inertia switch and 12 volts there... Here is my question, when i turn the ignition on, i have no power to the base of the Fuel Pump Relay.... Where does the power come from to power the relay???

I see several threads regarding engines that wont start for no apparent reason. My reason was a failed fuel pump relay. This sucker is hidden in the dash below and to the left of the radio. I got to it by taking out the ash tray. There are three relays under the cover. The upper left is the fuel pump relay. The one to the right is the turn signal relay. I don't know what the bottom left is for.

The #8 fuse under the hood was blowing on my '00 F-250 every time I turned on the healights meaning I would lose power to my park lights. The brown wire coming from the back of the headlight switch showed a dead short to ground that I traced to somewhere between the switch and the firewall.
Anyway, I got tired of trying to pinpoint the ground fault, so I cut the brown wires at the back of the switch and under the hood at the top bolt-on electrical plug and replaced the bad section with a new wire. It works fine now with the only exception being I do not get the park light flash when I hit the remote lock button the second time. I do still get the horn chirp.
My Haynes manual indicates there should be a relay box with a Park Lamp relay, Driver Unlock relay, All Lock Relay, and All Unlock relay. The park light relay looks like it sends the blip of power to the park light circuit. Where this relay box is? I'd like to splice into the brown wir coming out of it to restore the light flash when I lock the truck since sometimes it's too noisy to hear the horn.
Ford Super Duty (1999-2016) :: Fuel Pump Voltage Low?
Suspect I have a bad fuel pump. I checked for power thru the Inertia Switch. When I first energize the ignition I receive 12v after a couple seconds it drops to 7v. Is this normal? I checked at the connector to pump module and see the same reading. I swapped fuel pump relay and same readings. Just want to makew sure I dont have some other issue before doing pump.

I am looking for the location of the fuel pump relay on a 1997 Chevy S10. There is a bank of relays on the firewall on the passenger side, but I do not have any info on which relay is for the fuel pump.
I briefly looked at this vehicle where they had it towed to after it had stalled on the road and they couldn't get it to start.I had no tools at the time, but not hearing the hum of the pump, and no fuel at the test port on the rail, all pointed to a fuel problem. The owners boyfriend took over from there and replaced the pump this past Saturday and still no pump.
I suggested that he find the right relay and test it, but he skipped that part. Which of those realy are for the pump??????

I have searched through the site but have not found anything like the problem I'm having. I have a 2003 F250 5.4. Three weeks ago I attempted to start my truck and it just cranks. The fuel pump was not coming on. I left the truck over night and the next morning the truck starts with no issues. It ran normally for the next three weeks then the same thing happened again. Towed to the mechanic but the truck started up and ran. It shows no codes after both no starts and both times ran fine the next day. When running fuel pressure is where it should be.
