Ford Fuel System :: Stumble And Die After A Short Highway Run At 70 MPH / Fuel Injection Flooding Out?
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 :: 1986 F150 - Engine Running Rich / Flooding?
My engine is running rich, flooding? My truck is a 1986 F-150 302 EFI. The engine idles rough, black smoke and soot comes out the exhaust pipes, and black soot on spark plugs. Symptoms seem to disappear if I throttle the engine and hold it, but as soon as I release the throttle the symptoms reappear and in most case causes the engine to die. These symptoms have just started a week ago. What the problem is.
Fuel injectors are cleaned and rebuilt. New plugs and wires. All new fuel pumps and filters. New air filters. New fuel pressure regulator. New dual function reservoir. New 3-piece timing set. New O2 sensor. New EGR Valve and sensor. New idle air control valve. New distributor, cap, and rotor. New ignition coil. New high volume oil pump. New alternator. New pcv valve. New knock sensor and air charge temp. sensor.
Ford - Explorer :: 1997 - No Start / Flooding With Fuel
Ok so I have a 1997 Ford Explorer with the 4.0 SOHC .. The girl that owns it went out and started it to warm up and went back in the house , when she came back out it had died and wouldn't start .. I hauled to our shop and started diagnosing it .
It has spark
has fuel
Timing is good
Fuel pressure regulator is good
Crank sensor is good
About 62 PSI fuel pressure
No CEL
Seems to be getting WAY too much fuel and fouling plugs !
Replaced ECM ...same thing .
Used NOID light on injector wire and I have never seen one get so bright !
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 Fuel System :: Gas Went Bad - Cleaning Fuel System
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?

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.

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.

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.
Ford Fuel System :: 1990 E250 - Fuel Shutoff Switch Not Activated?
My '90 E250, open road, mini motorhome , says on the radiator mount , that there is a Fuel shutoff switch that may have been activated.... I don't have the manual for it, so I need finding the switch, so I can reset it ....The vehicle sometimes starts after about 2 mins with the ignition on, but today won't start, even after a longer wait. Both tanks are full...Fuel gauge not working , in either front or rear position. I can hear the rear pump,in the tank, but can not hear the front one....When I bought it last year, it ran fine after waiting to start, and both positions worked , no stalling , or shutdown.Came home about 95 miles, and it's been parked almost all the time since. I want to start it up weekly , but am having that same problem ...Today was the first time I could see the Fuel Pump Shutoff warning ...but can 't find the darn switch to try resetting .....

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 :: 1989 F150 - Hot 28 Psi Fuel Pressure Shuts Off?
for the past week we have been trying to figure out what is wrong with our truck. We recently bought it and it ran fine. Then got in a minor accident just a fender bender and it started acting up so I got towed to garage. First it would run when cold, but when hot fuel pressure would drop to 28 psi.
So I put new fuel pump, it started but still did the same thing hot 28 psi fuel pressure shuts off. So I put regulator on it, then had 0 fuel pressure won't even start. So got a another regulator thinking I got a bad one, still 0. Checked relay, there fine. I'm gonna check lines and see where fuel stops at but everything is new on it.
