Ford Fuel System :: 1992 F150 - Front Tank Leaks Out Of The Gas Cap - Truck Stalls Out
I have a 92 f150 w 302 . My front tank leaks out of the gas cap and builds up pressure. Even though I have never put fuel in it (owned it 7 mos). I siphon fuel out of it weekly. If I switch from rear to front. The truck stalls out.

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 2 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 Fuel System :: Start And Run For About Half A Second And Then Die
I have 1976 F250 with a 352 That will start and run for about half a second and then die. If I give it gas as soon as it fires up it sputters HARD and then dies after a total of about one to one and a half seconds. Is it getting to much fuel?
View 2 RepliesFord Fuel System :: Died When Start Up And Won't Restart?
Went out to start my 150 last Wednesday. It started up, then quit, and then wouldn't start again. Later that night, it started up and then kept running. Called up a couple of auto parts stores and was told it was probably the fuel pump. The next day, we got it running and took it into the shop. They couldn't figure out what the problem was, so we took it back on Friday. On Saturday, I drove it about 40 miles, then parked it for about an hour, then it wouldn't start up again.
The mechanic came and checked it, said it almost certainly was the fuel pump, then he got it started with some brake cleaner. I drove it home and then later drove it again. I made a stop and it wouldn't start again. Had to get it towed to the shop. They spent all day Monday changing the fuel pump and filter and thought it was fixed. I picked it up and had no problems that night. My wife drove it Tuesday about 50 miles and had no problems with stopping or starting it. I went to start it up Tuesday evening and it died again and wouldn't start up.
Ford Fuel System :: 1999 Expedition Will Not Start
I just replaced my fuel pump and sending unit in my 1999 Expedition and my truck still wont start.
Relays and fuses are all good.
Fuel safety shut off is not switched.
What the problem is?
Ford Fuel System :: Replaced Filter - Won't Start
Ok, I've replaced the fuel filter today and my truck still won't start. Checked fuses, and Fuel relay (19th slot). I've found the red fuel switch and it doesn't depress so I suspect it isn't tripped. I'm out of my league if I have a fuel pump problem.
View 6 RepliesFord Fuel System :: Continuous Crank But Does Not Start
My 01 super crew (4.6 liter) doesn't start. It sits in the driveway for weeks at a time, has 140k and has the orginial fuel filter. Before when this has happened, continuous cranking finally got it fired up. Could a dirty filter be the problem? This truck is 100% reliable so I'm really surprised. Looking at other posts, I see it only requires a special tool to replace. Is this so?
View 2 RepliesFord Fuel System :: Hard To Start When Engine Is Warm
I have a recently rebuilt 400 with a mild cam and Tmeyers flat top pistons. The carb is a 600cfm edlebrock that was bought new and installed a few months ago.
The issue I'm having is if I'm driving around and shut it off to run in the store its hard to start when I come back. I end up having to floor the gas to get it to start. When it's cold I tap the gas and turn the key and she lights right off. Could this be an issue with vapor lock? Why does it go away if I floor the gas?
Only other thing going on is when accelerating the engine runs noticeably smoother above 2700rpm. It's a little boggy below that. Probably two different problems but I figured I would throw it out there.

My truck is a 1990 Ford F150. It seems like when I let it sit for a few min that the gas just drains back into the tank and there for it wont start up that fast, it takes a while to get it going but when I shut it off and start it back up its like a new truck. It starts right up!!! Any tips on what might be wrong, maybe the gas cap is letting pressure out? Im 17 and my dad knows alot about trucks but he cant tell whats wrong.
View 1 RepliesTrans Sport :: 1992 Pontiac 3.1L V6 TBI Engine Refused To Start / Fuel Pump Relay Error Code
We have a '92 Pontiac Trans Sport with a 3.1L V6 TBI engine. Last Sunday evening it refused to start like someone left the transmission in Drive and the Park/Neutral switch was preventing it to start. There's the buzz sound from the fuel pump when you put the key on then nothing when you turn it to start the engine.
I checked the Park/Neutral swith by connecting an ALDL cable to the OBD port and it indicates correctly when I move the lever to Drive or Parking/Neutral. The only error code stored is "Fuel Pump Relay" but the Fuel Pump appear to be working?!
Battery is good, fuel pump fuse intact and the Park/Neutral switch appear to be working. How we can tackle this problem?
Ford Fuel System :: 1994 F150 Fails To Start When Turn The Key In Ignition
I have a 1994 F150 XLT 5.0 . The problem i am having is when I turn the ignition on I hear the fuel pump come on [both front and rear tanks] and it should stop when the system is pressurized but it does not,and the truck then fails to start. Intermittantly the pump does stop and the truck starts up.
There is fuel at the rail and there is spark,i have changed the filter ,fuel pressure regulater and the pump relay to no avail.
Ford Fuel System :: 1971 F250 - Gas Leaking - A Lot Of Crank To Start - Rebuild?
I have a 1971 F250 automatic with original stock 360 engine (100k miles). It currently has an Autolite 2100 2bbl carb.
The Autolite is leaking gas out somewhere where I can't see the leak. It takes a lot of cranking for it to start after sitting 10 minutes and my wife won't drive it for fear of being stranded. My attempt at a rebuild must have failed... Also have issues with anti-stall dashpot spring coming off while driving. When the spring and plunger come off I have to hold the gas on a little to keep from stalling while stopped at a light. A couple other parts looked like they needed repair during the rebuilt, but the kit didn't have any replacement (vacuum diaphragm torn). Also, after replacing plugs, plug wires, replacing points with Pertronix Ignitor 2, a new rotor, and distributor cap, it still doesn't hold a steady idle. In fact it is hard to get it down to the spec idle for an automatic without fear of stalling.
To make a long story short, what is a low maintenance 2bbl (new, not rebuilt) replacement carb. The truck needs to be dependably started by my wife for garage sale runs and home depot trips. I could switch to a 4 bbl intake, but would rather wait for another 50k miles and switch the engine over to a rebuild 390 with nicer intake and carb.
Ford Fuel System :: 1998 - Extreme High Initial Idle At Start Up
I have an issue with extreme high initial idle at start up. I took my 1998 Ranger with a 3.0L to the local dealer to have some work done about a month ago. Long story short, my number six plug wire got burned against the exhaust rail.
Anyway, I guess they re-flashed the computer to the newest *.bin, or flash version. After that when I start the truck the tachometer jumps up to 2200 - 2300 RPM and then it settles down to about 1500 after a moment or two, then it finally adjusts itself to about 1100 for a few more seconds and eventually ends up at 900 - 1000 RPM.
I confronted Ford about this and they said that Ranger's and F-150's do have a tendency to do that at start up. Ordinarily I wouldn't be too concerned, however I believe that the 2200 - 2300 RPM high idle at start up at 0 F, a bit much.
Ford Fuel System :: Hiccup And Stumble When Get On It Real Hard From A Standing Start
My 302 runs pretty good when all warmed up. It has some cold start issues every now and then, but is easily dealt with. My question is how to best "tune" the carb. It's a 600 cfm 4150/60 style Holley single pump, vac secondaries and electric choke. About as basic as you can get. I think I have the fuel level set correctly. I also think I have the "idle mixture" set right. I used a vacuum gauge and moved back and forth between screws till I got the highest vacuum. Is there a better way than that? I have the idle set correctly. the fast idle is a little high, but I can fix that.
Now, my real question is how to fix the hiccup and stumble I get many times when I step into it pretty good. I assume that this is the point the carb is going from idle circuit to main circuit. It stumbles when I get on it real hard from a standing start. I can roll slowly and step into it and it stumbles as well. I also like to blip the throttle when I down shift (it has a manual tranny by the way), and many times I'll blip it and get nothing. Now, it runs fine after the stumble all through the rpm range. That's the only time it stumbles. so, do I need more accel. pump shot?? To compensate on the transfer of circuits.
I also notice when I on it real hard, during the shift right when I jump on it, under the heaviest load, I hear a bit of spark knock. It's not running hot, and the timing is good. Do I need a bit bigger jets? I'm thinking it's going a bit lead during that time, but I don't have any real way to measure it.
