How difficult is it to change the fuel pump module?

View 4 RepliesI worked with my buddy troubleshoot and remove a faulty fuel pump. He received it a week or so later and did the install himself. After this, he states that while pumping gas at the gas station the nozzle no longer cuts off automatically when full causing overflow. He says this has happened at different stations and different pumps. I told him to go double check connections and that everything was sealed. I am wondering what could be causing it..

I have broken alum housing it looks bad , but still works. I can get two after market from rock auto for one 50.00 and anther for 60.00, the dealer is getting 160.00 what do I do?
View 6 RepliesMy brothers 2002 F150 4.6l has a starting problem of when he shuts it off it will be hard to start sometimes. If he lets it sit for a while it will start right up. I did a search a looks like the fuel pump modules are subject in these trucks. The search also have them mounted on a cross member by the spare tire, this truck does not. My question is where is the fuel module located on the truck?
View 1 RepliesI know this has been an issue for awhile and many may know about it but many probably don't. The issue is dirt and salt debri etc get packed behind the Fuel pump driver module rot it out and without warning you have a crank no start or worse it dies going down the road then you and the family are stranded or worse while towing on a trip. I made a video on how it happens and how to fix it with the solution Ford came up with. It is worth checking even if you don't seem to be having any issues yet......
View 5 RepliesSo the fuel pump module on my truck is falling apart, and I figured I might as well replace it....
View 10 RepliesFirst 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??
I ran out of gas one day refilled the tank and car still won't start. Took it to an mechanic he got it running ( saying it was the fuse and electrical problem) got it home and the next day it die on me again, so I called him up and he say it the fuel pump, so I got it replaced and it still won't start. So what's the next step on getting my car to start again.
View 5 RepliesAs I say in my first thread my 2000 4 runner don't start after I change the spark plugs. I don't get any fuel pressure from the fuel pump.
View 2 RepliesI was getting around 30+ mpg on the highway and 24-26 in the city, i got an oil change at the dealer ship and it reads 22.2 mpg..might go down to 21mpg but that is it....highway and city... It doesn't get any better or worse..
View 14 RepliesI am curious as to what are signs that a fuel pump is about to fail?
View 11 RepliesHad check engine light come on as the car stalled. Brought the 09 passat to vw dealer and was told the engine code showed fuel pump defect. For 1,000.00$ they changed the fuel pump and did a fuel system cleaning. Also had an oil change done.
Drove away less then 10miles, and the same thing happened. Bringing it back tomorrow, but how to handle the situation? Already contacted AMEX regarding the situation to potentially open a dispute charge claim.
If the MIL indicator is on, does it give a direct code to the problem? I suggested it could be the manifold issue, but they said that's not it.
The car quit on the road and I diagnosed a bad fuel pump. Multiple tests confirmed the pump had failed. While we were doing the diagnosis, I noticed some strange behavior when monitoring voltage to the pump. While supply voltage was present during cranking, none was applied to the pump when the key was first turned to accessory. I decided to chase one thing at a time and replaced the pump (and fuel filter, since it had been too long since last replacement and I wanted to "cover all bases").
After pump replacement, I opened the coupling in the supply line before the fuel rail to confirm proper operation. When the key was initially turned to accessory (multiple times to prime everything), there was NO fuel flow. When we then cranked it, fuel was present very quickly. After reconnecting the line, a couple of rounds of cranking got the fuel pressure up and the car started and ran perfectly. A quick VAG-COM check showed no codes. I test drove it and then shut it down. Immediately after shut down, I switched the key to accessory and the fuel pump started right up. After doing this 4-5 times with a few minutes pause in between, I pronounced the car "good" and finished up.
This morning, I jumped in, turned the key to accessory and heard......nothing. No fuel pump running for the normal 2-3 seconds. I cranked it and it took two rounds of 4-5 sec cranks for it to fire and run (normally). I assumed it needed time to build fuel pressure. I then drove it for 20 minutes, parked it for 45 minutes and when I restarted it, it took a longer than normal crank period (maybe 3 seconds) to fire and I did NOT hear the pump run in accessory position. The rest of the day was with short stops and I could always hear the pump start in accessory and the car always fired up instantly. I have the Bentley CD and analyzed the wiring harness. It looks like the fuel pump relay is only commanded to operate by the ECU - there is no external input to the relay coil I can see (ground or B+).
The bottom line is that SOMETIMES the pump is commanded to run in ignition switch accessory position and sometimes it isn't. The "isn't" always seems to be after the car has sat for a while. Is there any combination of failed sensors that would cause the ECU to NOT command the pump to run for it's few seconds in accessory position ? Obviously, the next step is the FP relay but I hate to just throw parts at the car without some sort of troubleshooting and the repeatability of the problem with sitting time leads me to believe it may be more of a relay DRIVE problem then the relay itself.

Car will not start. No sound from fuel pump while cranking. Pulled up the carpets and pulled the cover and connector from the fuel pump. Ive heard the relay is the common problem. I tried checking the voltages on the harness and we get 0 while cranking. Pulled the relay and we get a resistance from T pin to pin 86. I did notice a yellow color on the white connector on the fuel pump itself around the middle two contacts.
I have a 06 passat v6 with 34,5000 miles and with extended warranty,the car consumes about 14 mpg city and I noticed a humming noise coming from the back seat or bellow the trunk I am positive is the fuel pump, I will like to know if my poor mileage is related to the humming noise or should I take it to the dealer to have replace under warranty...
View 2 RepliesHit a bump in the road, car hiccuped then EPC and MIL illuminated. Scanned it with Carista and showed low fuel pressure. Looked under engine cover... Lo and behold! Connector is plugged in but male portion on regulator is snapped off!!! Needs whole fuel pump assembly at 25,000 miles!
View 3 RepliesI changed my fuel pump cause it died and now my mileage is about 100 less per tank? What could it be.
View 2 RepliesMore electrical gremlins. The car is a 2000 1.8t, it has had some running issues since I got it a few weeks ago. I replaced the ECM (had water damage), fuel pump relay and battery and it was running fine all week, my wife went to start it after work and it died when she took the e-brake off. I went to her work to get her and noticed the rear marker light was on when the car was running. Got the car home and now it wont run for more than about a minute and the light comes in when the fuel pump is running, turn the key but don't start the car and the pump and light come on for a second and go out. Start the car and the light stays in until the car dies.
Is there anywhere in the system these two circuits are connected? Do they share a load relay anywhere?
So at 55,200 miles, the fuel pump on my 2003 decides to quit today. I never got a Recall Letter and when I called VWoA in the past about it they said that my car was not one of those affected, even though it was within the years affected. So what do I do now?
View 6 RepliesMy wife was driving our 08 B6 yesterday and suddenly had a loss of power. Check engine light was on. Took it to the dealer and we heard back today that the high pressure fuel pump had gone out. I had heard of the TDI's having this problem and I know BMW had to do a recall on the same issue. I didn't know that the 2.0 TSI had this problem.
I'm a little bit concerned 'cause we leased the car for 3 years and didn't have a single problem. I thought it was very solid so we decided to buy the car last month Now my confidence in the car is a little bit rattled.
The car is under warranty. I just hope that this is not the kind of thing that's going to go out every 20K miles! Out of warranty, this repair would have been costly.
My 2003 Passat 1.8t starts up but turns off 1-2 secs later. And if it is the fuel pump, where is it on my car?
