Ford Excursion :: Fuel Pump Died After Rough Running Randomly
Nov 4, 2016
I have been chasing down what was a perceived vacuum leak...
My Ex (V10, 4x4, 217K miles) started to have an intermittent rough running/no power situation very randomly. No codes on the scanner, and no real apparent cause or condition to pin it down. I noticed what sounded like a like throttle ping...figured it was a vacuum leak someplace in the spaghetti under the hood.
I began to run down the possibilities. I have recently had the entire suspension replaced and upgraded all 4 corners to Power Stop brakes. Figured it might be something related like the classic lines to the hubs.
Replaced the vacuum lines to the hubs - ran OK for a bit, then rough start/idle/no power.
Replaced the vacuum switch for the hubs - ran OK for a bit, then rough start/idle/no power.
Replaced fuel filter - ran OK for a bit, then rough start/idle/no power.
Ordered a new vacuum reservoir...
While waiting on that, changed all 10 plugs and coils. Not. Cheap. Ran OK for a bit, then rough start/idle/no power.
Replaced IAC - ran OK for a bit, then rough start/idle/no power.
As I was getting ready to install the vacuum res, it just croaked. it would turned over like it wanted to start, but wouldn't catch.
Of course.... So, now it had to be towed and yes, the fuel pump puked and that was that. I've never had one do anything but just quit suddenly before, so lesson learned. Evidently these pump can act up for a bit before they die.

First it was the whole spark plug debacle. Now it's the "fuel pump module". Story starts a several months back. On a moist day I was headed out and the truck ran very rough, "clunky", like it wasn't getting gas. After 15 miles and a stop truck ran fine. Didn't think much of it and truck ran fine for month or so. I was then away for a couple days and came home to find my truck wouldn't run (started briefly then died). Local mechanic thought it might be a fuel pump issue but then got truck running thinking it might have been a delayed inertia switch in front panel (I had hit a deer a week or 2 prior). Again, not thinking much of it continued to drive truck with no issues for awhile. Then one rainy morning on my way to work the truck was running very rough and "clunky" again. It died several times and finally for good.
After getting it towed to the mechanics, he figured the fuel pump was finally shot. The end to my long story is it was the fuel pump module (luckily a lot cheaper fix than the fuel pump) - half of the housing was gone (corroded away) adn moisture was shorting the pump electronics. Why, if this module is half encased in plastic do the engineers feel the need to encase the other half in metal (appeared to be cast aluminum)??!!????!! Of course it makes sense to have an electrical unit that is mounted underneath the truck where it can collect all the moisture, snow, salt from the road encased in a corrodable metal housing. No no, don't put it all in plastic, just half of the unit. MAKES PERFECT SENSE!! I thought to be and engineer took some sort of brains and common sense. Must be not at Ford. I can't be the only one with this issue and wondering WHY!!! - it must be widespread??

So, I just had the fuel pump replaced on my '15 6.7 a month ago and it just died again. (next day edit: it didn't actually die, it showed all the same symptoms)
Same symptoms: whining sound, low fuel pressure warning, reduced power warning.
This time I'm 50 miles from home so I pulled off the road before it shut off. Interesting, I was in a hilly area and my low fuel warning came on too. We are waiting for a tow. I was considering trying to push on but don't want to get stuck in a dangerous spot on the highway. We're in a church parking lot.
So, last time this happened I was on flat road with about a half tank of fuel on a lunch break. I ran a mile after the warnings came on to feel out the issue and to see what would happen. I happened to be only about a mile away from my dealer so I drove that way. I got reduced power warning and then it cut power on me (limp mode). I made it to about 100 yards away before it cut off.
This time, I was in a hilly area at night on a windy two lane road with no shoulders in the woods. I was miles from civilization and was showing below a quarter tank of fuel. ~100 miles to EMPTY. I got the low fuel pressure warning first and then the reduced power mode before the whining noise started. I was climbing a hill on a curve at the time. I drove a quarter mile and then pulled off the road into a parking lot so I wouldn't be stuck on the shoulder. It didn't actually go into limp mode.
I let it sit a few minutes, talked it over with the wife and decided to call for a tow. After talking to the tow truck driver who said he would be an hour because he had to go find a bigger truck, I decided to see what I could do while I wait. I fired it back up and the fuel level dropped to below 1/8 and I was now showing 33 miles to EMPTY. I was parked on a hill with the back end up. I had backed the truck into a space to make it easier for the tow truck driver. I let it run a minute, checked for leaks and it seemed to run fine with no studdering or additional warning lights.
CEL was on but no new warnings. I put in my code reader and pulled the P0087. Just one code. I revved it a bit to see if there were any issues. It seemed fine so I decided to try my luck. I started driving towards home with the intention to stop at the first diesel station to fill up. Truck ran fine. After two minutes of driving gently, heart racing, my fuel level came back up and it now read 88 miles to EMPTY. I drove 11 miles to the nearest station and filled up. No issues. I shut it down. I fired it back up. Still no issues so with a full tank, I drove home the remaining 30 miles without issue.
Planning to take it in to the dealer Monday to get it checked. Could this be from an air pocked due to low fuel level and hilly terrain? Is my new pump dying already? Is there something else going on inside the tank or elsewhere?

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 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?

5.4 L, Engine runs if primed at the intake. Fuel pump can be heard running but no fuel gets to the engine. Truck is mint and being sold real cheap due to this issue.
Fuel Pump? Filter? Both? I haven't seen the truck, a friend is considering buying it and rolling the dice it is a quick fix. Fuel is in the tank .....

My brothers 2001 is having an issue with the fuel pump. It has a random no fuel pump basically the fuel pump does not come in, he turns the ignition off then back on and you can then hear the fuel pump turn on and the truck starts and runs normally. I'm not looking forward to dropping the tank to replace the sending unit so I was thinking maybe the relay is the issue? I'd eater do that than a sending unit job...

On my way into work this morning, my 06 with the 5.4 started running very rough/shaking at low rpms. I could kick it out of overdrive and it would smooth out and seemingly be fine at higher rpms.
This worked out for a couple of miles until the truck just died on me completely. The Edge is showing po351, 352, 353......358 codes. Ignition coil Primary/Secondary circuit fault on every cylinder.
I'm thinking its unlikely that every coil failed simultaneously....computer? When I try to start the truck, it will try to hit on a cylinder or two, but will not run.

I have a 2003 Ex 6.0 psd, 155k miles, and was on my way to work to a site 40 miles from nowhere. I was about 10 miles from my destination cruising around 65 when the Ex started losing power. I would say within a couple of miles power was gone and i had no choice but to pull over. I popped the hood, got out had a look around and saw no leaks or anything out of the ordinary. Let it sit for a few minutes and tried to restart it to no avail. There was no check eng light or any signs something was wrong.
I just so happened to have my OBD scanner with me and plugged it in and read for any extra codes. Three popped up on the screen: P0232, P0263, and P0278.
P0232 Fuel Pump Secondary (Feedback) Circuit High Voltage,
P0263 is described as a cylinder number 1 contribution/balance. In essence, this code is stating that the number one cylinder in the firing order is experiencing a fuel-related problem.
P0278 same as above for cyl 6.
Right away i thought the fuel/lift pump took a dump on me and was causing the fuel issues in the two cylinders.

I drove my truck 2 times the day it stopped running. The 3rd time I tried to leave it started moved about 2 ft, spit and sputtered and died. It had blown the fuel pump fuse. I changed it and checked the fuel shut -off in the cab, passenger side. It was not tripped. Tried to start it and as soon as I turned the key it blew the fuse again. I changed the fuse again and this time I changed the fuel relay and the switch in the cab. Turned the key and it blew the fuse right away. Went to AutoZone because they are close to the house described what it was doing to them and they said sounds like a short in the fuel pump.
I purchased a new pump put it in turned key blew the fuse, pump just clicked...I found this site and my son noticed a thread where it said wires under the cab are good for wearing through and grounding out. I looked and it did wear through one wire coating. We taped it up, put extra cover over it and now it does not blow any fuses. Fuel pump still just clicked. Took fuel pump back for an exchange.....same thing. Turns over but fuel pump will not pump fuel. What am I missing?......

My 2001 escape recently decided to act up, it was running rough for a little while and then it died and would only run intermittently after that. I found the #3 coil was bad and the egr valve was broken. I replaced those and now when it decides to run it runs smooth but when you give it has it bogs down and dies and doesn't want to run again for a while. I also put on a new fuel filter and the fuel pump sounds like its running good. I know I'm missing something here but I can't seem to figure it out. Also there are no DTC's at all. I really need this car to be back on the road again.

2002 F-250 SD V10 Auto Trans 140K miles.....
Engine ran fine until battery died. Vehicle then sat from Nov to May with no battery in it. On start up now after install of new battery, engine initially surged at idle and seemed to miss (run rough) in gear/under load. No CEL or codes. After a single short drive idle and running under load seemed to have improved a bit, but not yet back to what I would call normal.
QUESTIONS:
Is this simply a matter of the computer having to relearn after battery disconnect?
Will driving restore things back to where they were/should be?
How much driving/How far?

So last night I was on my way home, was going through 2nd gear when all of a sudden my car sputtered and just died. It will keep cranking but just won't run. I have a SE 6MT. Had it for 4 months and almost 11,000 miles on it. Tow it to the dealer today, they went through the car and determined it's the fuel pump and will be replaced under warranty.

My jimmy died on me yesterday on my way home from work...i thought the fuel pump went because i couldn't hear it when trying to restart... I had about a quarter tank of regular in there,,,put in 2 gallons of super and it started, but died again about a quarter mile down the road...got it home with a push...after searching for and checking any fuses i could find...swapped relays on firewall and all seemed well....i heard the pump and it fired right up...went walked, just in case) and got another relay, and now i don't hear the pump again,the battery is a bit low now,,,so maybe a jump would give me enough juice? I'm going to jumper the wires/relay...and be sure the pump is working... I'm sure it is.. 94 jimmy 4.3 vortec 140k I gotta pick up my wife from work later and don't want to get stuck again...

Just did a complete engine rebuild on 2003 Explorer. All back together....have new battery, starter working, spark at plugs lol crank but no start. Next check is fuel. Fuel pump WAS working fine when timing chain guides went about a year ago...(had to rehab 2 parents and finish bath remodel before pulling engine) So... 1 year later I can't seem to get the fuel pump to work. I checked all fuses and relay. The fuel gauge is working - full tank.

I just got my Bosch fuel pump from Riff Faff and will be installing it this weekend.
I want to add a Pre and Post filters to the pump and had a couple of questions
1) the threaded end that's under pressure what is that connection.. I would like it hard connected to a filter and then the stock line connected to the out put of the filter.
2) for Pre Filter its a push Lock connection... Should I keep it or look for something that works better under Vacuum?

Before I left on Spring Break last week, truck wouldn't start. It was a Saturday morning, so I had it towed to the only open shop in town. He said the fuel pump was going out. He got it started maximizing the fuel pressure with his scan tool.
The unusual thing is I replaced the fuel pump (I have a V-10) earlier this year with a Motorcraft Pump from Amazon. I also replaced the fuel filter about 60,000 miles ago.
Does this sound right? I have never heard of turning up the pump with a scan tool.
It did fine over Spring Break, but is in my driveway right now refusing to start. I can't believe the fuel pump went out that quickly.
Does it sound like the fuel pump?

This is the second time this happened to me. First time was about two weeks ago where i was just driving and the car stalled. Tried to start but it sounded like it just wasn't getting fuel. Brand new battery, terminals are clean) Got it started and it was revving high like a cold start, normal but why after driving for 30 mins? EPC light came on also which was strange along with the CEL, a buddy checked the code and it was for the secondary air injection pump. (I have not had that go off in a while. Code po4011 secondary air injection. Had this issue a while ago with that code when i did a short ram intake. Tuner cleared it so i can pass emissions. ) Now today it died about 2 miles from my house. Same thing but no CEL. EPC light came on and car was revving high, luckily 3 cars behind my buddy was there and he give me a push into the gas station. Once again it wanted to start but i felt like no fuel. waited a few minutes and it started right up again until it almost died in my drive way. Cluster comes on when it dies. ignition is good.
My big question is the stalling part and the EPC light coming on, then the car revving like it is a cold start but not stopping? and i need this car to be working.

As in a previous post, i have been having issues with my truck starting then immediately dieing if i dont keep my foot on the gas.
Ive learned how to drive with 2 feet because of it, but I'm afraid i might be doing some type of damage since it keeps dieing and I have to keep starting it.
Once i get going for about 10-15 minutes its fine but its happening every time i start the truck.
Before it starts running correctly, it only idles around 400 rpm.
I think its the fuel pump, since my mechanic put a code scanner on there and it didn't throw any codes, he thinks it might be the fuel pump.
My question is, should i go with a ford pump from the dealer or are the ones sold from discount/o'reilly/napa just as good?

Have any of you tried to cut an access hatch in the rear of your truck to get to the fuel pump without dropping the tank? Am I way off? can it even be done? My fuel pump took a dump with about a quarter of a tank. I'm trying to find a work around.
