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 Fuel System :: 1995 - Stalls - Now Stop Moving - Fuel Filter?
I have a 95 F150 4x4 reg cab long box with a 302 V8 and dual tanks... I was driving around yesterday when my truck started to lung and then the motor stalled... when I stopped moving I tried starting the truck and it started with no problem, so as i kept on my way, about 5 minutes later the same thing happened and it stalled again, (I have an automatic by the way). but this time before it stopped moving i pump the gas a few times and it fired back up and then stalled again... i switched from my front take to by back maybe thinking it could me my fuel pump in the tank but it did the same thing again about same time later... Would it be my fuel filter on the frame (like in line fuel filter) or why is it doing that? its EFI by the way.

I have a 98 K1500 Z71, having trouble with a ABS brakes going off every time I come to a stop, occasionally I don't even have to push on the brake just turn a corner and they go off. The brake light or the ABS light on the dash don't light up. I have taken the speed sensors off front axles cleaned then and sanded the rust off where they mount and still the same problem. Also, in the world of OBD scan tools, I know what ABS stands for ( brakes ) but what SRS stands for?
View 6 RepliesFord Fuel System :: Backfire Then Die When Step On The Gas At A Stop
Truck is a 74 250 390/auto tran. 2wd. When I am at a stop and then step on the gas (not hard) it will sometimes backfire then die. Then I can start it up and it'll run fine. The only other times it backfires is if I am doing about 40 or higher, take my foot off the gas, and let it coast down to around 33mph or so then step on the gas it'll backfire once and run fine. If I am at a dead stop and punch it it will also do some backfiring, usually killing it.
Other than these times it runs fine. I've adjusted the carb (I know not correctly) and that does work if I set the idle higher. Is it possible my fuel pump is going bad? I was always told a mechanical fuel pump pretty much either works or doesn't. If it is a possible pump problem should I test it or just replace it...
Ford Fuel System :: Bogs Down When Go From A Stop Or Even Slow Down For A Turn
i recently got a 86 f250 351w ho. My problem is when i go from a stop or even slow for a turn then reaccelerate it bogs down and i have to pump the pedal to keep is going. My first thought was the accelerator pump but now I'm thinking power valve? I believe this carb is a Holley 4180?

I have a 2000 Expedition that hesitates and sometimes stalls when taking off from a dead stop. The problem is not consistent and therefore hard to diagnose. I have had it to the dealership and two other mechanics and none of them have been able to fix the problem. So far they have replaced the intake gasket, fuel filter, EGR and PCV valves and have changed the PFE sensor and connecting lines. It seems they are just throwing parts at the problem and haven't a clue what is wrong. There are no error codes in the computer.
So far I have spent around $1,500 on this problem and it is not any better from when I started and it might actually be a little worse. I seem to think the problem is in the fuel system and not electrical because all lights and gauges function normally when the problem happens. I can also sometimes produce the hesitation by shifting the transmission into second gear while going around 50 mph then giving it a good bit of throttle after the engine revs. What could be going on.
Ford Fuel System :: 1987 - Loss Of Power / Black Smoke And Also Dying When Stop
So my 1987 Econoline Van was running fine until recently we noticed loss of power going up the slightest of hills and it will only hit 55 max with gas to the floor. Its shooting out black smoke and also dying when we stop. We are getting very poor fuel economy as well.
We got a tuneup, oil change, new air filter, etc. We also had a few electrical issues due to a short we thought we had fixed completely... So I'm wondering if it could be the timing? Cause it'll idle low, then high, then bog down and lose power...
Also was thinking maybe bad fuel pressure regulator or fuel pump....but how would I check this? And since we did experience a short, could we have blown a sensor too?
Nissan - Pathfinder :: 2002 - Take Long Time To Start - Fuel System?
My wife's Pathfinder (a 2002) has developed a problem with slow starting. The car cranks well (even at -20F, so it's not a weak battery) but takes a long time to start. It might crank for 5 seconds before sputtering to life. After being driven and shut off, most of the time, it will start up instantly again, just like it used to before the problem started. The problem is intermittent in that it sometimes starts pretty quickly in the morning, although it's not the instant start that it used to be, it might only crank for 1 second or less. I know that sounds like a normal time for a car to crank before starting, but the Pathfinder used to start, almost literally, instantly after the key was turned. So, even 1 second is an uncharacteristically long time.
What I've done:
-- Replaced spark plugs
-- Swapped the starter relays with identical relays under hood
-- Replaced fuel filter
What I haven't done:
--Replaced fuel pump
--Replaced fuel pressure regulator
Both of these are somewhat big jobs (I think I can handle both of them) and more expensive than what I've already done, so I'd like to get some input on where the fault could lie before picking one. Or, am I completely off base thinking it's fuel system?
Ford Fuel System :: Location Of Check Valve That Maintains Fuel Pressure On The System?
I have a '99 E-350 6.8L. Where is the check valve that maintains fuel pressure on the system?
I have been experiencing a starting issue when the engine is hot. Cold starts are usually fine. I've replaced the in-tank fuel pump (pump only, not the assembly) to no avail. I was out of town and didn't have access to a fuel pressure gauge when the problem started so I couldn't say what I had prior to replacing the pump. But now, with a new pump, when I check pressure, I get about 40 psi when I first cycle the key on, but it drops right back to zero as soon as the pump shuts off. If I cycle the key on a few times, sometimes I can get it to hold pressure at about 32 psi, and it starts fine. When I shut if off, it goes back to zero psi, sometimes gradually, like a bleed down, and sometimes immediately.
My conclusion from this was that the check valve was bad. I was told it was part of the in tank fuel pump assembly. Since I didn't replace the entire assembly, this made sense. So I just dropped the tank back down, but I don't see anything as part of the pump assembly that serves as a check valve. There is a rubber nipple on the end of the return line, but I don't see how that can hold any significant pressure.
So, before I go out and spend another couple hundred bucks on the complete fuel pump assembly, which apparently can't be purchased without the actual pump, I thought I'd ask. Where is the check valve that holds the pressure in the fuel system?
BTW, I also have replaced the fuel rail pressure regulator, but it made no difference (I went there first since that was much easier than dropping the fuel tank a second time).
Ford F-150 (2009-2014) :: Driver Side Window Randomly Stop Working From Time To Time
Having problems with the auto-up feature on your windows? Mine seems to randomly stop working from time to time. Only the drivers side has the problem. When the truck was new the dealer re-programmed the computer and put a new window switch in. That worked for a while but the problem keeps coming back. I can easily do the re-programming sequence however the problem always comes back. I have a 2012 Lariat SCREW.

I went to move the 2000 yesterday and it will not start because the gas went bad. It has been sitting about 6 months, since it did not snow this past winter. How do I go about cleaning the fuel system? I was thinking suck the gas tank empty with an electric fuel pump, and blowing out the lines with air. Does this sound right?
View 7 RepliesFord 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 :: 4180c - Fuel Coming Out Of Primary Vent Tube
I have a F-250 4WD with 7.5L which has a MC/Holley 4180c sitting on top. It was getting very poor mpg (like 5-6 miles/gal) and then was getting harder and harder to start. This progressed rather quickly to not starting with fuel coming out of the primary vent tube. I suspect it has to do with the primary float stuck open. I was considering rebuilding the carburetor. Is this over reaction prematurely or is there something like float adjustment that may rectify all of the symptoms described. If a rebuild is in order what is the information I would need to ensure getting the correct rebuild kit. Info that I have so far from research is it is Motorcraft ID #E5HE-9510-MC.

What would make a FI engine act like its flooding out and dying after a short run on the freeway?
Details:
1994 F-350 351W (just overhauled this winter)
has new TPS, ICM(?).
Dual exhaust dumps right before the tires
new filters in tanks, new fuel filter on frame rail
All fuel lines have been opened and blown out from the tank to the engine compartment fitting near firewall.
Fuel pumps hold good pressure when tested.
Symptoms:
smells like its running rich most all the time
after a short hiway run @ 70MPH it will stumble and die when returning to surface streets.
fuel smell near engine sometimes, but no obvious puddles or leaks anywhere.
May be related?:
When on a longer highway run, I can't use the FWD tank for a long period without the engine stumbling and cutting out or popping at times. But I can swap to the rear tank for a bit then run the FWD tank again for a while. driving up hills it seems to be worse, but I'm in the panhandle of TX right now..good grief!
I am having to drive this truck for work long distances. While I dont expect a vast fuel range, it would be nice if I could go a couple hundred miles on 20 gallons of gas....
Ford Fuel System :: 1976 F150 - Fuel Draining All The Way Back To Tank
My vehicle:
1976 F150 2wd Extended cab
390 4bbl
c6 transmission
4BBL Edlebrock Carb
Dual fuel tanks, only rear main tank connected
My problem: For the first year I owned the truck, everything ran fine and it started up really quickly even after it sat for a few days or a few weeks. I have since, for about the last year or so, had to crank it for 30-45 seconds to get it to start. This all started around the time my fuel pump went out. I replaced it with an Airtex fuel pump from Autozone. I also installed a glass in line filter before the carb in front of the distributor.
I noticed that after about 4-6 hours, the fuel had drained out of the filter and that's when I would have to crank it forever to get it going. It also seems like there is no fuel in the carb as it doesn't even try to start when it first gets cranked. I thought this was a bad pump, so I bought a new one last week and tried it again. Sure enough after about 4-6 hours, everything is empty again and it takes forever to start it. So it's not a bad pump, or so I think.
The other day I backed it into my driveway and left it, something I never do. I checked about 4 days later and there was still fuel in the filter. This makes me think that gravity is making it drain back to the tank.
Is there something that would cause this? Also I have found a one way fuel check valve online that is supposed to remedy this type of problem. Do they work for this situation? Or is there something else I should be doing to fix this? It has taken a bit of a toll on my starting system having to crank so long all the time. I have so far had to replace my starter, starter solenoid, and all the battery cables, starter cable, terminals, etc. due to excessive wear.
The valve I found is here : [URL] .....
Ford Fuel System :: Changed Fuel Filter Now Just Cranks But Won't Fire / Start
2002 E-250 with the 4.6 V-6. Pulled the 30 amp fuse, replaced the fuel filter, replaced the fuse, now the truck wont start. Checked the fuse and the kill switch under the passenger kick cover, all ok. Cranks and cranks but wont fire. No problem prior to changing the filter. Even swithed out the relay with another, no luck.

View 1 RepliesFord 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.
