I dont know if this is an issue, but here goes. You know the fuel pump prime sound when you open the drivers door? The buzz? It has recently stopped. Should I be concerned? Is this a foreshadowing of hard times to come? Or am I just over analyzing?
View 12 RepliesMy R is garage kept, and every morning when I open the door, I can hear the fuel pump make a quick priming run. Well, not "every morning"; sometimes it doesn't do it's two second prime, and when that happens the car usually takes two cranks to start.
(I know that there is a timer. If you have been driving the car, shut the car off, close the door, and then open it, it is not going to prime, but I'm talking about after the car has been sitting all night.) This issue could be related to my door-lock-craziness issue.
I'm fixing a 2007 Sonata that was in a front end collision, I've replaced everything that was ruined in the wreck (as far as I know), and also replaced the SRS control module, impact sensors, and also the airbag. The car starts with starting fluid and there isn't any damage to the engine so I'm not concerned with something being wrong with that, but the fuel pump won't prime and before the wreck it drove fine. So what could impede the fuel pump from priming? I've checked the wires and they're not sending power to the fuel pump so I feel like the pump should still be fine, it's just it's not getting power. What could cause this?

View 9 RepliesI'm having a situation here. Yesterday I decided to clean the MAF in my 01 VW Jetta 2.0, so without disconnecting the battery I unplugged and took the MAF sensor out and sprayed it using "CRC MAF sensor cleaner", let it dry for about 30 to 40 minutes and then re installed it. When I tried to start the car, I opened the ignition (ON position) and didn't hear the pump priming, still tried to start the car, it when on for about 2 seconds at rough-800rpm idle then rpms dropped and car stopped running. Then, I tried to started it again a couple of times more and I still don't hear the fuel pump priming and the car will crank but not start.
Did I ruin/blew the fuel pump or something in the system? I don't understand what could have possibly gone wrong. I already tried searching for it but did't find the exact same situation and though details might be important.
So after pulling her apart again to clean up the bay, she finally decided she didnt want to start:
- Ignition works
- Cranks for days
- Fuses look good
I noticed my fuel prime doesn't go on when I open the door and the secondary water pump isnt on after I turn the key off. I have an inline fuel pump, so wouldnt that supply fuel if the in-tank one was dead?
There is a noticeable whining sound coming from the back of my car. I searched and the closest thread I could find talks about whining at speed, but this is happening even at idle. From outside the car it is much louder. It goes away sometimes, but comes back pretty quickly. I restarted the car at a red light and the noise stopped, but by the next light it was back. Seems to be happening at speed, too, although that's harder to hear over the sound of the car.
Pulled codes, and the code P310b keeps coming back, even after cleared. The car has had a dead battery for probably the last 6 weeks, and was restarted two days ago, maybe 100-150 miles since restart, plenty of warm up and cool down cycles, but the code keeps coming back. I never noticed the sound before I let the car sit, and I didn't notice it yesterday while I was driving it around (although maybe I just had the music too loud???)

1- Does is sound like this could be the low pressure fuel pump?
2- Do I need to be concerned?
No more fuel pump priming sound upon opening door but the car still fires up without any problem. And yes it was after the car sat for a day or two without being started. I kind of got used to that sound and was like now that it is gone. Should I be worried my fuel pump is on the way out?

View 2 RepliesI'm rocking a 2005 Ford Excursion with the 6.0L PSD. When the Ignition key is switched ON prior to starting, the injectors cycle in a priming sequence.
What I need to know from owners here, is how does that sequence sound to you? Does it start slow and then increase in speed until it's complete, sounding like a rise in pitch? Or does it just make the same sound the whole way through?
Trying to debug a random no-start and I'm trying different theories. Current suspect is the FICM, despite the OBDII always reporting 47V - 48V. For me, the priming sequence starts slow and then runs faster until it's complete. Trying to figure out if it should sound the same the whole way through.
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.
View 3 RepliesIt's a 2007 Nissan Murano with 50k miles and I've had it about 2 years. Occasionally, it won't start and this has happened about 7-10 times in 2 years. It turns over and makes all the normal sounds of starting, but never catches and starts the engine. Normally I wait a few minutes, try it again with some pumping of the gas, and it will start. I take it to Midas for oil changes and told them about it - they said the computer revealed nothing.Yesterday it would not start and I had to have it towed 90 miles home. The tow truck driver said he could not hear the fuel pump "priming" when he turned the key or, he said, it might be a fuse. Two hours later when he delivered it to my home and got off the tow truck, it started.
View 10 RepliesMy car was performing poorly then Stalled while driving, no start since. Put starting fluid in open throttle body for 5 secs, then tried to crank.
fuel pump doesn't turn on (can hear it) for 2 seconds When the Ignition switch is in ON position, You can hear it when cranking in Run position though. So this makes me think that Its not building enough pressure
Pulled it out, hooked it up to a 12V batt and it works.
Someone else changed the spark plugs. Fuel comes of of the line just before the fuel rail. Doesn't squirt like there's a lot of pressure.
Pulled the injectors clean them put them back in with new O rings. Fuel only came out of 2 injectors when cranking.
Pulled the spark plugs check for spark while cranking. They all spark. Put new ones in.
Pump does send fuel when cranking which means the pump, and pump relay should be working I assume.
I've been driving 93 ranger 3.0 4wd since last fall. first week I went to start and fuel pump relay had blown. I put a new one in and been driving since fine, till today. Now when I try to start, if it starts it will run fine all day as long as you don't turn it off. If you turn it off and restart half the times it will pop relay again. My fuel gauge has been stuck on full since I bought it also. I'm wondering if maybe pump has got had to start and drawing too much current...

R's at the dealer today for a faulty fuel float sensor, and they just called to let me know my vehicle has the wrong fuel pump in it. Seems mine has the pump for the Golf/Rabbit with the 4 cylinder engine and they need to keep the car until the part is in.
View 16 RepliesI recently had my fuel pump replaced in my 2005 GTI ... twice. Both times, the fuel gauge no longer shows a full tank, and doesn't show empty tank correctly. Is there some way to reset the gauge? Is the pump somehow tied to the gauge, or did the mechanics mess the float up when they changed the pump? Sadly I had it repaired somewhere other then the dealer.
View 1 RepliesI have a raspy exhaust leak sounding noise when I start my 2003 GTi 1.8t that cuts off just a few minutes after I start the car and a fellow owner told me he thought it was a vacuum pump that has rivets that fail and allow the case to separate and cause this noise. Where this pump is located? This former coworker of mine said he replaced the rivets with long slender screws and nuts after removing the rivets but I lost contact with him and don't know where this pump is located.
View 2 RepliesSo, 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?
The truck now makes a whining sound for about 30-40 seconds on a cold startup from the fuel tank and def tank area . what could this be ? Its at the dealer for other issues also , the dealer said that it was my starter making the noise, I'm pretty sure the starter is attached to the motor and not located by the fuel tank....

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.
