Passat (B5) :: Fuel Pump Has No Sound While Cranking, Car Won't Start
Dec 21, 2010
98 Passat 1.8T FWD
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.

Ok so I disconnected the fuel line and the fuel pumps when I turn the key to on and when I crank it it's not pumping gas ..
Changed the relay
Changed the crank pos sensor
I'm at a loss what would cause the fuel pump not pump when cranking?

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?

A friend of mine have a 94' Explorer with the 4.0 v6. Fuel pump starts for 2-3 sec when i turn the key, stops when cranking and starts again when i stop cranking. i checked the fuel shutoff switch and it was ok, and it have spark.

B5 1.8T - A few weeks ago, I had some battery issues. Long story short, I ended up changing the battery. A few days later I began to have an issue with my coil/ICM. I decided it was probably a good time to do the delete and conversion to 2.0FSI coils. Before doing that, I used a generic hand held scanner to clear codes and see which would come back just to have a baseline for after the conversion.
At this point, car is not starting at all and I'm getting smell of fuel after cranking. I pull out plugs and see they are soaked with gas. I probably shouldn't have, but at this point I went and converted everything over, expecting that when I was done it would start....
Meanwhile, at this point the car cranks but doesn't start, and it seems as if fuel is dumping into the cylinders. Hooking up to an Elmscan5 and Scantool software, I get absolutely no codes (it IS connecting to ECU to some extent). Im not even able to get the cable to work at all with VCDS lite..
So I have NO codes and a car that turns over but wont start and smells strongly of fuel when I'm cranking it.. I am reluctant to buy anymore tools or software at this point; I'm thinking maybe I fried the ECM, or could it be as simple as throttle body adaptation?

I 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..

99 escort 2.0 will not start. Has spark, fuel pressure, and 100 psi compression in each cylinder. After cranking for awhile , pull the plugs out and the plugs are wet with fuel. There is no answers anywhere on the net, but apparently there are others like this out there. No codes also.

1999 Savanna 1500 van. This has been a great Van, only has 70,000 miles and has never let me down until a few months ago in February when it was getting down to -20 degrees F. Seemed like it was cranking fast so I thought it was timing. Turned out there was no fuel pressure so first put the relay in, that didn't work so we dropped the tank and put a fuel pump in. This seemed like it cured the problem but I only drove it 200 miles until mid May when it did it again.
The security light wasn't staying on so we thought it must be the ignition switch. That didn't fix it either, we just got the ignition switch back together (not the actual switch but the wiring harness) and it's not starting again. It will start after some anguish and cursing at it. Seems like messing with the wires going to the fuel pump or hitting the cover over the fuel tank will cause it to start. I haven't checked it yet but I can guarantee it doesn't have any fuel pressure.

01 7.3. Cranks, won't start. Tank was at 1/4 but is full now. The lift pump runs, I can feel and hear that the motor is spinning when I cycle the key. I removed the fuel filter and cycled the key and get no fuel into the bowl. It looks like the lines are stainless from the pump to the tank so I doubt it is sucking air. I pressurized the tank with a shop vac and I get fuel coming into the filter housing. Am I missing something obvious? I have never seen an electric pump that would run and not pump fuel. I removed the suction line at the pump and don't feel any suction there.

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 had the head gasket replaced along with all the other gaskets that come in the kit. new radiator, water pump, thermostat and thermostat gasket. blew head gasket at 78,000 miles. So now that has been taken care of, slowly everything else is going bad. recently, i pulled up in front of someones house and my suv turned off. When I tried to start it again it made a clanking sound and would not start. AAA'd it home and pulled the timing cover where the source of the sound was coming from. Seen the tensioner pulley loose and the belt loose. got it back on tdc and still does not start. the cranking over sound is lagging and sounds whiny. thought maybe was out of gas so i got gas and now when i try to start it it still is winding but it backfired and there was smoke behind the upper intake and still wont start. It wants to start, but doesn't.

This past winter I started having trouble with my '06 Santa Fe where I would turn the key to start my car and nothing would happen. No cranking, no clicking, no sound. My lights turn on fine, radio, everything else works just fine. Sometimes it won't start for 30+ minutes, and sometimes I'll just try a second time and it'll start up right away.
Last winter when this happened my check engine light came on and so I took it to the dealership and they said it was the crank position sensor that needed replaced. For whatever reason I didn't get it fixed and have been driving my car with no problems whatsoever for 10 months or so, until this weekend when my no start issues started again. The check engine light is on again and it's the same code for the crank position sensor.
I believe I will definitely get the crank sensor fixed this time, but could the issue possibly be anything else? Bad starter? Ignition switch? My mechanic can't give me a definite answer because every time I take it to the shop it starts up just fine for him.

I drive an Infiniti i30. When I bought it, the guy who sold it to me told me that the car runs great but that I would have to turn the key kind of hard to get the car started. Over time, this problem has progressively gotten worse. There have been times where I'd be stuck in a parking lot for over an hour trying to get the car to start. When I turn the key, I can hear the starter clicking, and all of the dash lots and radio will come on but the car doesn't sound like its cranking or even trying to start. The weirdest thing is that the first time I drive my car in the morning it starts up just fine. It's once I turn the car off after driving somewhere and try to start it again that I have problems. I'll have to turn the key 100 times or more sometimes to get it to start if its not the first time of the day. What this could be?

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?

When I turn the key, nothing happens. no sound, except maybe the fuel pump. the battery is fine. the starter motor is also fine.

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???)
APR Stage 3, APR LPFP.
1- Does is sound like this could be the low pressure fuel pump?
2- Do I need to be concerned?

I have a 2004 MY05 Jap built AWD RX330 that won't start. It is almost 12 yrs old & has 115k miles on it. This is the very 1st problem I've had with it.
Some quick checks indicate that it may be power supply to fuel pump or fuel pump itself. No sounds from it when turning ignition on.
Any wiring diagram for the 5 pin plug for the fuel pump? I'd like to put a meter on it or connect 12V to the pump directly before I remove it.

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?

What updates were done to the 3.6 engine for 2008? So far in 100 or so miles I've noticed that the 2008 3.6 is:
Much easier to start. (06/07 requires cranking much longer to start)
idles smoother (06/07 shook a little when sitting at idle)
accelerates smoother
then the 2007.5 3.6 I had, and the 2006 3.6 in my friends Passat.
Both of those did have the OJ update done. The only visual difference is the plastic engine cover. On the 06 and 07 it has a silver colored cover. the 08 has a black cover that is different in shape.

Lately my '03 1.8t with 90k has taken to long cranking before firing.Once it fires, it runs rough for about two seconds and then smooth as usual. Thought it might be Fuel pump relay but I'd think that'd show a fault light. Same with Fuel pump?No faults showing up. Plugs changed 9k ago. Only run Premium Shell.

I drove two days ago. Yesterday I didn't drive. I just walked out to start my car and it won't start. It keeps cranking (click noise). The lights are turned on, locks response to my remote, radio works, but I noticed the clock was set back to 12:00 and it's 4:00pm right now.
Two days ago, I noticed my car hesitate a little when I accelerated to 35-40.
I drive a 99 1.8 t Passat
Turns out i needed a battery replace. my battery was having 67 amps compared to 500 requirement.
Question: Does low battery life cause the car to hesitate (like as if the cylinder misfire) at 35-40 mph acceleration?
