Ford Fuel System :: 1989 F250 5.8L Runs Great Then Dies After Warm
I just purchased a 1989 F250 with a 5.8 motor. Great truck for its age. Ive owned other Ford trucks in the past and my Dad had them as a kid. Love them.
When I bought the truck from the 2nd owner it had a problem so I bought this truck with the problem figuring with my past knowledge I could fix it. Not the case. When I got the truck it would start fine and run really great but when it got warm it seems it would die and I would have to wait till it was cooled down to start back up and again it would run fine. Well the problem got worse and worse and now it wont run at all.
It will run on starter fluid so that leads me immediately to the fuel pumps. I say that plural because none of them will run it seems. I did a fuel pressure test at the shrader valve at the top of the motor on the fuel rail and I get no pressure at all when I turn the key. The relay in the engine compartment seems to be working to as I can hear it. I put a new on of those on to to be sure. Leads me back to the pumps again. I replaced the external pump on the fuel rail and I know thats working. I replaced the fuel filter to while I was there.
Is it possible to have BOTH fuel pumps in the front and rear tanks go at once? Seems unusual. My other F150 with dual tanks worked great and when the back tank pump went I could just switch it over to the front tank.
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...
View 4 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 9 RepliesFord Fuel System :: Small Leak Where Filler Neck Ties Into Rubber Hose That Runs Into Fuel Tank
I recently purchased a used 1999 F250 Super Duty with about 150k miles on it. The truck runs great and I have no complaints but there are a few things that need to be taken care of. It looks like there is a very small fuel leak where the filler neck ties into the rubber hose that runs into the fuel tank. There is a thin film of diesel along the side of the tank, on the leaf spring, the air bag and various other places. Nothing is dripping. I want to drop the tank and replace the hose. The Haynes manual says to depressurize the whole fuel system--is this really necessary if I don't plan on doing anything to the system aside from dropping the tank?

View 4 RepliesFord Fuel System :: Engine Runs For 10 Seconds Then Dies
I have an 84 Bronco II with a fuel injected 302 in it. I was out wheeling with it the other day, and it was doing great until about 3:00. I got out to see that my brothers radiator had sprung a leak. When I got back in my Bronco and put it in gear, it just stalled. I started it back up and it ran for about 10 seconds then shut off. It kept doing that over and over again. Finally, I got tired of it and had someone get my truck and tow me out of there. Why would it run for about 10-15 seconds only and then shut off like it was getting no fuel (yes, it does have fuel in it)? I have a feeling it might be fuel pressure regulator valve because it was acting up a while ago..

I have a 92 chevy pick up 5.7 with 159,000 miles. The truck runs and starts great but shortly after I bought it 3 years ago it developed a sort of misfire at higher rpm's, it's fine if I drive it normally but if I try to pass someone it will downshift then fall on it's face, (spit,sputter and slow down). some times I can feather the accelerator and it will come back again. I normally don't drive the truck in the winter but this week I was forced to use it and the cold weather is seriously affecting it, it took forever to get it up to 70 mph after getting on the highway. once up to speed it will do 75 all day without an issue.
I've replaced the plugs, wires, pulled the throttle body and cleaned it as the port for the pcv valve was plugged solid with carbon. I have not replaced the cap and rotor as they seemed to look fine. I have not checked the fuel pressure because it will break the tires loose upon take off and I don't think that would be possible if the pressure was low, would it?
Ford Fuel System :: 1977 - After Rebuild Runs Rough - Mixture?
I just had a former Ford tech rebuild my motorcraft 2150 2v on my '77 F250. I took it home, put it back on the truck and it ran kind of rough. I then went ahead and screwed both idle mix screws in untill seated, then back out two turns. The truck ran great, turned off truck then when it the house for dinner. Half an hour later I come back out...truck will not start, just sits and cranks. Finally got it started and it ran good, but crapped out after it warmed up. I have made sure there were no vac leaks when truck was running the first time. Did I adjust the mixture right?
The truck is a '77 F250 400/C6
Prius (Gen 3) Fuel :: Engine Starts Up And Runs For About 4 Minutes
My Prius waste gas by always starting the engine. Even with the battery indicator at full charge. Every time the Prius is shut down, like leaving the car to go into the store for 3 minutes or more or backing Prius out of garage, the engine starts up and runs for about 4 minutes, regardless of being fully charge or not.

View 6 RepliesFord 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 - Explorer :: 2002 - Either Stalls Or Starts - Runs Rough And Then Stalls With No CEL - Water In Fuel?
We've had two problems within the last week with our 2002 Sport Trac (4.0l SOHC engine w/167,xxx miles). They may be unrelated, but I suspect there's good change they are. Both incidents happened while my 16 yo daughter was driving, so there's only very limited info on what happens. Both times, when I get there, it starts and runs fine. There is no CEL.
The first time it apparently stalled as she neared her destination after driving only about 2-3 miles at 35 mph or less after a cold start. She was slowing to pull into a parking lot and reported the dash lit up with warning lights, no power steering assist and no power brakes and no power from the engine. When I arrived it started and ran normally. She had fulled up the day before after two days of heavy rain, so I suspected water in the gas. I drove it more than 200 miles within the next 24 hours under a variety of conditions and filled up at a different station. I experienced no problem what-so-ever, and didn't bother adding any dry gas.
Then 5 days later (still on my fill-up) when she tried starting it after sitting all day, she reported the engine started but ran rough before stalling and never idled normally.
Doesn't the fact there's no CEL eliminate a lot of the upstream part of the control system......like sensors and actuators? This leaves things like the downstream parts of the fuel and ignition systems. I.e. from the fuel tank / pump to the injectors and the downstream parts of the ignition system.
What are the possible culprits? Fuel pump, fuel pressure regulator, injectors, ignition module, spark plugs, and....... what else? (I'm not that familiar with what these engines have) And of the possibilities, what are the most likely causes.
Ford Fuel System :: Truck Starts Choking And Stalls After 10 Minutes Or So Of Driving
My truck starts and runs fine cold. after 10 minutes or so of driving, it starts choking and stalls. If you try to start it, it will not. If you wait about 3 minutes, it is fine, starts , and drives ok, for about 3 minutes. I have replaced, plugs, fuel filter, battery, and a ignition module, as well as cleaned the opening of the throttle body
Ford has ordered a fuel pump, I am thinking it could be the
-Throttle position Sensor?
-MAF sensor?
-fuel pump?
It puts out code p0191 for low fuel pressure. Ford is scheduled to install new pump in am, but I don't want to spend a grand if it is just the TPS or MAf?

View 4 RepliesPhaeton :: Bad Fuel Pump - Keep Losing Power And Runs Out Of Fuel
Stuck 398 miles from home. Car kept losing power, running out of fuel (even though I had a quarter tank). Stopped and filled it, but could only barely get to next exit. Step on gas- no go. Let off gas, car catch back up and run. Wife noticed definite new sound in back. Took her many miles and comments before it finally sunk in and I remembered the same groaning noise from a fuel pump going out on a cabrio. So, fuel pump bad.
Am preparing to go out and jump terminals, as per bentley manual. That should tell if it is transfer pump or fuel pump. My main concern now is are the pumps under the rear seat or in the trunk?
By the way, I made it to a motel (lucky enough one that accepts pets!)
