I have a 1994 Ford 460 motorhome with a intank fuel pump that quits when it gets hot. so I was thing of butting a heavy duty in line pump on and just pull it through the old pump can this be done safely. Or is it best to drop the tank and just put a new fuel pump in.
View 10 Replies1994 150 300 6. parked truck after lunch finished work and it wont start no fuel comes out of the valve. Can't get the pump to work even when jumping the 6 pin. heard the relay click still nothing. Checked the inertia switch it wasn't popped. Took the pump out jumped it straight from the battery pump works . I know there has to be something i am missing...
View 7 RepliesI'm looking at replacing the fuel lines in my 94 F150 and the big question is what to do with hooking up to the fuel lines coming out of the fuel pump hat and the fuel rails? Ford uses a specialized pressure fitting on it's custom fuel lines. I think there may be some third party fittings that would replace these, but I'm not sure. I could use a standard hose and cable clamps, but I just don't trust that kind of connection for a fuel line.

View 10 RepliesThis 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?
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?
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.
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 RepliesI 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 2 RepliesI was letting my truck idle to work on a cooling issue when I noticed oil coming from my fuel pump! What would cause this? It wasn't coming from were the pump bolts to the timing cover it was coming out of the side of the pump it looked like? I'm going to get a new one.
View 7 RepliesHave a 95 Bronco with 5.8, I turn the key on and fuel pump doesn`t shut off. Changed fuel pressure regulator still no shut off. Changed relays, no luck. Have 38 pounds pressure with key on, but no start. Checked spark just in case, and have fire. Don't know what to try next.
View 10 RepliesIt 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 RepliesPulled codes awhile ago...got a 96. Says "Fuel Pump Circuit Open"-Battery to ECA (1988 On). What is an ECA maybe the Pump Relay? And does this thing have a fuse for the fuel pump in the panel. Fuel Pumps not getting any juice.
View 1 RepliesWorking 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.
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?
View 2 RepliesMy eXcursion is showing the typical signs of a failing fuel pump. It cranks and fires on a few cylinders, then quits. I released the schrader valve on the fuel rail but very little pressure is released. From these indications, and after checking for a blown fuse, it appears the fuel pump is going. I say going because it did start after this happened, but would you trust it?
I ordered a new fuel pump, it's due in tomorrow. I remember seeing instructions on how to drop the tank but can't locate them with the search function. I'm also concerned with how to remove the pump from inside the tank. I know you have to spin off the big plastic ring, how do you get the pump off the bottom of the tank?
A cousin has an old 1994 Ranger. The fuel pump relay, located in the engine compartment fuse box. went bad, so he got a new relay.
Now, it does not plug in securely, so sometimes he has to open the hood and fuse box and wiggle it to make contact.
Ideally, one would probably replace the fuse box, though that would apparently involve a lot of wiring, right?
How to "cob" this up so the contacts will make better? Perhaps something to put in the slots to increase pressure on the blades?
Maybe gently twist the blades so they go in at an angle? Maybe touch the blades with a solder iron and put on a small blob of solder to make the blade bigger? (Though it seems to me that solder is not a good contact material?
Maybe solder to the blades, a very small piece of brass or similar material? Put a piece of aluminum foil over the blades?
Sometimes after running my 94 Limited, it doesn't want to start - it does crank - like it's not getting fuel. I have found the work around and want to know if it would be fixed by replacing the fuel pump relay.
The symptom is just after starting, it starts to run poorly, and then dies out, then will not start at all. I use to keep trying to start it for 20-40 minutes and suddenly it seemed to work.
It seems the work around is to turn the key to on for about 5 seconds and then turn it off - then it starts and runs as good as ever.
So, is this a symptom of a bad relay? I thought I'd start there because of the cost of the relay is fairly cheap. 1994 Explorer Limited 4x4?
I have a f53 motorhome and 4 out of the 8 injectors pulse. The front 2 and the back 2 don't pulse. The middle 2 on both sides work perfect. Why would they not pulse and only give out positive on the two wires to the injector on the one that don't work. The ones that work they pulse.
View 8 RepliesMy 1986 Ranger 2.9 starts only when I spray starter fluid into the air intake. It does stay running and it drives fine. The engine will not fire up unless I do this process. I have cleaned out the fuel rail, fuel injectors, purchased new fuel filter, and tested fuel pressure (which is good).
