Ford Fuel System :: 1991 F250 XLT - Fuel Pump Will Not Stop Running
I just bought another 1991 Ford. This one is a 1/2 ton XLT Lariet with the 302 and for the first time I own a short bed. I also have a 1991 F-250 XLT with a 460 and a 8' bed.
Here is the problem, ( I think) it will not run or at least not for long. The fuel pump, which I am guessing is in the rear tank will not stop running. On the F-250 the pump stops running after a few seconds after I turn on the key.
Where should I start to find out my problem with the fuel system?
Ford Super Duty (1999-2016) :: F250 - No Power To Fuel Pump Relay
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 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.

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.

I had a fuel leak at the pump cover (I straightened the cover) and am ready to install the new diaphragm. The old one came out with the rivet head side upward and the pump lever riding on the protruding pin side. Which is correct? This is on an 85 F250 with a Motorcraft carb.
View 1 RepliesFord Fuel System :: 1987 F250 - Swapping Out Mechanical Pump For Electric?
I just purchased an 87 f250 w/ a carb'd 460. I purchased it with the mech fuel pump swapped out to an electric. The previous owner states that they gave him the wrong electric pump and I should exchange it for a different one. The reason for him putting it on was to get it running for me to hear it run.
My question: Is this even recommended? I wouldn't mind staying with an electric pump up front. If it is recommended, what would be a suitable pump to replace it with, as in flow/feeding characteristics?
Also, it only feeds from the rear tank, which also has a bad fuel pump. I'd like to get both tanks functioning again. I'd rather not deal with the tank switching valve due to what I've read about them. Has anyone ever hooked up a manual valve and just switched tanks that way? I've searched this site extensively and couldn't find anything. I know I'm not the first to have thought about it.
Ford Fuel System :: E350 - Fuel Tank / Pump Noise After Cutoff
This van has had a couple of fuel pumps, no surprise there, and i need to look through my paperwork and find out how many miles the current one has on it, but it has the STRANGEST habit I've ever had on any vehicle. Starts fine, runs fine, no fuel pump noise when van is running, and when you turn it off, the fuel pump creeks on and off for several minutes.
I mean a strange creaking noise almost like a shorted electrical device or a vehicle's brakes when you park it on a hill and the breaks creak as it settles into place. I'm probably doing a lousy job of describing this but i don't know how else to describe it!
ALSO, if you lay under the van and wait til it stops creaking, you can tap the bottom of the tank and it will creak for a few more seconds. You can tap repeatedly and make it creak more. Is it about to explode? Can i trust it on a road trip?
Ford Fuel System :: 1979 F150 - Fuel Pump Leaking From Side?
I've had a fuel leak near the pump of my 79 F150 with a 400 for some time. I didn't know exactly where it was coiming from, but fuel was being sprayed on to the oil filter from something near the pump. I assumed it was the steel line, and that it had rusted through or cracked, and was going to replace it when I had a chance. I was poking around today though, and realized that the fuel was not leaking from the line, but from a hole in the side of the mechanical pump.
For someone who knows what these pumps look like, there is a horizontal cylindrical bump out near the top of the pump, on the side of the pump that is away from the engine. The fuel is spraying in a mist out of one side of that. To me, it always seemed to be a screw channel, but I didn't think the pump was 2 halves put together? Need to know more about my pump, what that bumped out section is, or why/how fuel could be spraying out of it.
Ford Fuel System :: 1987 F150 Fuel Pump Runs After Key Is Off?
Why the frame mounted fuel pump might run after the key is turned off? Then when you turn the key on it may or not run. If it does run it keeps running. shouldn't this shut off after pressurizing the line? is their a pressure switch in the pump that's failing? This has the 3 pump system...

I have an 87 F150 4x4 4.9L EFI with a single tank. Fuel pumps keep running even when the key is off. I tried swapping relays but the problem still exists. The engine will start and run OK for about 15 secs. then die. I installed a new low pressure pump, high pressure pump seems to be OK. I also installed new fuel filters. I dont want to just throw parts at this truck, where do I go from here?

View 10 RepliesFord Fuel System :: Fuel Pump Runs Constantly
It started out w/ my wife swapping from the front fuel tank to the rear tank due to the fuel qty getting real low. Then the next day when I drove it I had bad fuel qty and amp meter indication, I found a blown fuse on my fuel qty/amp meter gauges. I replaced the fuse and got my indications back. Now I hear my front tank fuel pump is running constantly when selected to its position. Its now full of gas and still runs constantly. The rear tank/pump operates normal. I am wondering if I ran that pump empty and lost its prime? What is the best way to burp it?

View 1 RepliesFord Fuel System :: No Fuel Coming From Pump Nozzle?
Working on my cousin's 84 F150 351w HO with a Holley 4180 4bbl and auto trans.
I rebuilt the carb because of sticking floats (that and it was filthy and sitting). It fired up and I drove it to my uncle's shop a ways down the road before even adjusting anything. At the shop, it fires right up, idles great and floats and idle mixture screws are now adjusted.
It has a dead spot right off of idle that's been driving me crazy, and stalls in gear if I'm not careful with the pedal.
After reading around here, I looked down the carb to make sure the fuel was squirting as soon as the throttle moved, and noticed there was NO FUEL squirting from the nozzles. So that explains the dead spot...
There was just the needle, then the nozzles, then the screw that went in, same as they came out (only cleaner). Wondering where to go from here to get these working again. Going to pull the nozzles off and see if there's anything obvious going on in there.
Ford Fuel System :: Pump Not Drawing Fuel
Ok so my son and I are new to this whole truck restoration thing, but we're eager to both learn. We recently scored a 77 F250 camper special that's sat for about 14 years. When we bought it it was running. The previous owner had done quite a bit to clean it up. When we got it to the house we drove it around a bit for fun, and parked it until we could drop the tanks to clean them out. That's done, we've replaced the fuel sensors in both tanks, the lines are clear based on us blowing air through them from the engine side back to the tank side before connecting to the tanks. The mech. fuel pump is brand new and seems to have suction when we turn the truck over. We've installed a fuel filter before the pump in an effort to filter any possible residual junk out of the lines, but we can't get fuel to the engine! (Yes we put gas in both tanks.) The truck will run when we run a line Direct from the pump to the a gas can, but not when connected to the tanks. What could we be missing?
