Ford F-150 (2004-2008) :: Buzzing Noise Coming From Fuel Pump But Not Enough Power To Turn Over
Feb 13, 2012
I have a 2005 F-150 supercrew 4.6L with appx 127,000 miles on it. Back in December i took the family to a drive in movie and left the ignition turned to the on position. I jumped the battery and drove a few miles home. The next morning when i tried to start the truck it would not turn over. There was a buzzing noise coming from the fuel pump but not enough juice to turn the truck over. This has happened a few times in the last couple of months but will jump and run fine for weeks at a time. I've taken a 2500 mile round trip to Texas with no issues. I took a 200 mile trip this past weekend and now it will not start. I'm thinking it could be the fuel pump relay? I went to the parts store and bought a relay but it's not the same size as the one in my Haynes Manual. The part from the store is the same size as the bigger relays in the kick panel fuse box but does not match any of the plugs. According to my manual the fuel pump relay should be a smaller relay.

On my 06 Mark LT I have a buzzing noise of outside air coming in the cab on the passenger side. I have had the grinding vent door actuator problem fixed in the past so I am not sure if it is related. The buzzing gets louder as I go faster, such as on the highway. Where to look?

Ok I have recently bought a 1998 Ford F-150 V6 4.2L 2WD and when the guy sold it to me the check engine light was on and he told me that randomly when you turn the key to the on position you will not hear the fuel pump buzzing sound and he knew it wouldn't start, he said you would have to turn the key from the on and off position many times until you hear this sound and then the truck will start and run fine.
First off I got the codes read and there were three of them P0171, P0174, and P1537 some things to note are that the drivers air bag looks like it had deployed, the cover is loose and when I pulled it back the air bag looks duct taped up inside there that would cause the air bag light to continuously flash while driving. I noticed the battery leads were corroded so I replaced the battery and put new battery clamps on both wires, after that the problem did not happen for a week and I though it was over but it happened again.
Next is that the truck has the PATS system and it did not come with a remote which I have also read that the PATS system can cause the fuel pump not to turn on but not sure if this would cause it to not start randomly because sometimes it starts right up. When I started to look at the simple things to fix I noticed it did not have an air filter in the housing. so I thought the MAF sensor could be dirty so I cleaned it with the special cleaner, I put sea foam into the intake via a vacuum hose and also have put a fuel system cleaner in a full tank and have driven most of the gas out. After putting in an air filter, cleaning the MAF sensor, and sea foaming the intake, it seems to run a bit better but I am still having the random fuel pump issue.
I have checked the fuses and the and the fuel pump and ECM relays both are fine. Today I put new exhaust on it because it had some bad exhaust leaks and the truck did not start again, so the guy trying to put my exhaust on, hit the fuel tank with a hammer and it didn't work then hit it again and it finally worked. Im not sure if the hitting it did it or if it just randomly turned on like always from turning the key on and off. The new exhaust has made a huge difference in driving it feels and sounds much better.
Also to note is that when I am stopped at stop lights it will idle at about 1500 and then it drops down to 500 and back up and back down again and it does this at most stop lights, and it is not an abrupt drop it just slowly idles down and back up again. Again once the truck is started it runs perfectly fine with no issues, and there are no specific times when it has the problem it seems to be randomly. I know that many people will tell me to change the fuel pump out and I am already prepared for this but if there is any easy things I haven't thought of yet...

I have about 500 miles on my 2008 R32, and today I noticed while sitting in the car with it running that there was a noticeable buzzing coming from the fuel pump. It sounds like it is coming from the pump under the tank itself. Hear this coming through to the cabin? Rather loud, I wonder if this issue has already been reported with other 3.2 VR6 setups.

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 .....

The last two mornings I have gone into my garage and have heard a faint "buzzing" noise that seems to be coming from the rear of 2013 RX350. Given the location of the noise, my first inclination was that it was possibly the fuel pump running a cycle for some reason. But when I heard it for the second day in a row, I figured it would be wise to ask if this is normal or something I should take up with the dealer?

I have an 01 Accent GL 1.6L. It will not turn over. Battery, terminals, and wires are all new. Alternator is also good. There is a buzzing noise coming from beside the cold air intake. I'm not sure what part that is. The part that is buzzing is where the cam position sensor is connected to. It also has wires that run into the firewall.

The other day, my father-in-law was driving my '91 Explorer and it just died on him. I assumed that the fuel pump quit becuase it wouldn't come on when the switch was turned on. I had a brand new lying around so I dropped the tank and put it in but it still won't work. I checked the inertia switch and it wasn't tripped. There is no power coming to the new pump at all. When the switch is turned on, there is a noticeable "click" inside the engine bay. Would that be the fuel pump relay making that "click"?

So the fuel pump module on my truck is falling apart, and I figured I might as well replace it....

Tried to start my truck after sitting for 2 days in sub zero weather. wouldn't crank. pulled the batteries and charged them over night. Tried to start it the next day-wouldn't crank but the starter relay clicked. Was going to pull the starter and check it but decided to replace the relay first. replaced it and tried to start but now have no power to the cab-nothing comes on. I've checked the batteries with a load tester and they are ok. I've checked the fuses and they seem to be ok. when I tried to start it and the relay clicked there was a loud buzzing noise that seemed to be coming from under the dash. it has done this before but this time was louder than usual. I live out in the sticks so taking it somewhere is a last resort. It is a 1999 7.3 with 290000 miles.

2001 F-350, 7.3L,
Has done this off & on for a few years and am tired of it! Noise is kind of a buzzing that seems to come from the flasher/turn signal relay. It stops buzzing when you turn on a turn signal, activate the flashers, or lift up on the shifter arm(?). Had to drive home yesterday with the flashers on! So I see from researching that it may actually be the multi-funtion switch on the steering column. So I removed that, cleaned up all the contacts, and put it back on and the buzzing did not go away.

ok i was just driving my 2004 ford f150 truck and it stopped running. I turned the key and it started back up again and then while on idle it stopped again. I took it too auto zone and it showed a code of p1237 which as far as i can see says fuel pump secondary circuit failure. does that mean i need a new fuel pump and how hard is it to replace.

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??

My 2001 4.6L F-150 has been sitting on the driveway, used once every 2 weeks or so for the last 3 yrs. I came to start it a few days ago and it kept turning over but not starting. The key security chip is working, battery is charged, all plugs are firing, fuel pump fuse and relay check good. When I turn the key to ON, sometimes I hear the fuel pump priming, other times it doesn't. The times it does prime, the truck fires right up.
The times it doesn't prime, engine won't start. When the pump does prime, and while the engine is running, the pump makes a noticeable buzzing sound, much louder than normal. When the pump primes. fuel pressure measures at 42psi in the ON position, 36psi with engine running, and 46psi with engine running and vacuum hose removed. I believe all these are within specs.
My question is this: Is it safe to assume that the pump is going bad and will eventually fail completely? My second question is (and I know this can be debated til the end of time) should I get the Motorcraft or aftermarket? I have Airtex, Spectra, Carter, and Delphi available locally.

So I'm stumped I have an 04 6 liter and I have no power to my fuel pump. My fuse under my Dash is good which is a 20 amp fuse which is number 40. My inertia switch is not tripped and I have power to it however my fuel pump does not have power what else could it be? Is there a relay somewhere else?

I have a 2003 Hyundai Accent with 166K on it. A couple of weeks ago I drove it and for an hour and parked, then after several hours I tried to start it and it wouldn't start. I had it looked at and found out that the fuel pump was not buzzing. I replaced it, it started and I drove it for a couple days then it died and didn't start again. It cranked but wouldn't start. To get it to start again, I had to spray starter fluid and then was able to drive it home. A couple of days later, while I was idling at a traffic light, it died. The engine cranked but it wouldn't start. I used starter fluid again and got it home. Once I use starter fluid it runs fine, like nothing is wrong with it. There is no fault code present. I replaced the fuel relay, fuel pressure regulator, ECU, fuel filter and spark plugs but I still have the same issue. What else do I need to replace? The car will start sometimes and sometimes it won't. Sometimes it will start fine without starter fluid and then other times when it randomly shuts off, I have to use it. I was going to replace the crank positioning sensor but since the car starts with starter fluid I think it may have something to do with the fuel.
