Tiguan :: Low RPMs / Almost Stalls - Bad Fuel Pump?
Jan 8, 2012
Every so often when I leave the car sit for 30 minutes after being driven, I start it up, put it in reverse and back up, then when I put the car into drive the RPMs drop for two seconds or so and it seems like it wants to stall. After that happens, all is well and the Tig drives normal.
I scanned the Tig and it came up with a "low fuel rail/ fuel pressure" code. It happened 5 times.
Is my fuel pump going? Maybe a dirty fuel filter? Or maybe a computer problem?
Info: Tig has 26k miles on it, stock computer (not chipped), it is out of warranty. I only run 93 octane in it too.

This car now has 6k miles .
A lot of people including me, has fuel pump failure. That's not bad you say..and no it's not if that was the only problem. When it fails, all metal particles that are shredded inside travel through your whole fuel system. Your fuel tank, your fuel lines, etc. Basically everything from your fuel tank to your fuel injectors. They replaced close to 50 parts on a brand new car!!!
When this happens, the car stalls completely which is now a safety issue! Imagine driving 2 kids on a highway and your car shuts off, giving you very limited braking (IF ANY) and steering!

I have an issue of fuel pressure I believe on my 2003 3.5 Santa fe...It would start then stall...I'm at my wits end with this thing...I checked the relay and its good...checked all fuses and they are good...I don't hear the 2-3 second whine of the pump when I turn the ignition to the on position, so I suspected a bad pump...but before I bought a new pump I took out the back seat, removed the access cover and checked the connector to see if the pump is getting power...its not...I'm at a loss as to where to look next...

Motor has been stalling intermittently since May. Finally had the fuel pump replaced last Friday (8/17/12). have been driving the car back and forth to work since then with no problems until yesterday. Made a run to the local convenience store and the car was shut down for about ten minutes. Came back out and car would not start! Gave it about 10 minutes and then it started again. Got it into the garage and let it run for awhile and it stalled out. Got the check engine light (a first for that) so swapped the fuel pump relay with one of the same part number. Fired right up and did not stall out.
Also, check engine light went out on its own. Swapped relays back to original positions, motor started right up, stayed running and check engine light went out on its own. What could be causing my problem? Since check engine light came on then went out on its own, would there be any trouble codes to read? One other thing, original relay has pinkish residue on the pins. What could that be about? First time poster so I hope what I have typed out makes sense. 2003 Accent 4 door with 1.6L DOHC motor. Approx 79000 miles.

Well I had the dreaded loss of power and EPC/Check Engine light happen on Monday. Was driving down the Interstate and all of sudden we just lost power. It did not go completely dead, but it ran like crap. Called the local VW and they advised to bring it in, still under warranty (27k, 26mths) and it turned out to be the high pressure fuel pump. They replaced the pump and the replacement was bad! Luckily they tested it before they got it out the door back to me. Provided me with a loaner and the dealer had to get a replacement pump overnight. Picked up the car yesterday and everything drives the way it should again.
I had already had the software update, but according to the service advisor that was for the fuel pump in the tank, not the one on the engine. Not sure if that is correct, but that is what the advisor told me..

I have been without my dub for over a month mk4 gti/golf awp motor 1.8t manual transmission and have ran multiple scans and replaced multiple parts. I am suffering from a no start condition, start and stall immediately, and have troubleshot many problems.
Most recent vcds scan results are: intermittent door module fault (not faulty, not implausible, "intermittent") (j386) Speed sensor implausible (g28) (already replaced with no change) open circuit or short b+ fuel level sensor fault.
I have had the driver side door taken apart on multiple occasions and found: no cracked joints on the pcm of the LOCK module (solder covered by brownish/gold sealant?) Two breaks, 1 in the ground and 1 in the hot wire between the chassis and the door and since applied electrical tape to the chafed part of the door wire harness. I have ran multiple scans since applying the tape with various results.
After applying a maintainer and verifying full charge on BRAND NEW BATTERY I ran scan with above codes.
I have in the last month replaced coolant temp sensor, fuel filter, fuel pump relay, above mentioned battery, and installed toggle switch to lock module micro-switch, speed sensor. About 5-10k miles ago I replaced the fuel pump with vemo brand from ecs tuning and fuel pump relay.
I have re "seated" and cleaned all terminals, below and on the battery as well as on the transmission, have "checked" the ground just in front of the ecu and removed enough parts to place my hands on it to check for a loose condition. Also checked ground on top of block next to coil packs. I've checked pillar a for chafing and the ground next to pillar A and the ground just below the CCM.
I have also taken a mallet and attempted to re create this door slamming condition by tapping everywhere around the door jam on the chassis and door with no change. Also with the door LOCK module removed, I have tapped on it to see if pump would prime, no change...........
After sitting in my recaro imitation cloth seat totally defeated I realized that the intermittent fault code was pointing the "integrated window motor/DOOR module" that was the only thing I hadn't attempted to "test" (originally thought window motor was only a window motor)
Verified continuity to the door module, and verified continuity to relay panel, fuel pump and lock module........... Also tapped on the DOOR module itself with no change.
Piece the whole door back together, slam the door and bam fuel pump primes........... (also massaged the repaired-chafed wires before and after re-installing back into door, with no change/prime.) After sitting a while sometimes it will prime by itself......(with any of the 3 fuel pump relays I have for this car)..
Replacing 1 fuel part after the other over the 4 years I've owned the car has temporarily resolve my issue, until now. (Also have tapped around gas tank/retainer ring on the pump to see if fuel level sensor fault was a culprit). I don't believe this to be the issue because I've netted this fault in the past and has never cause a no start condition or come back after clearing when replacing fuel related part.
After slamming the door I have noticed the pump primes in waves, like a hum hum hum instead of 1 solid hmmmmm and when the car DOES start (when the pump primes) the pump continues the hum hum hum condition before dying. (I have gone as far as a test drive and I rev the engine and put in gear but acts as if i have a bad clutch, all rpms, no horse power like it's slipping condition from a bad clutch
immo light goes off when key in on position, epc and check engine light are off after car STARTS when slamming the door. With key in on position hear a loud click under hood (relay station I'm certain) but the throttle body buzz's until the chime sounds with door open (have not tested this when it DOES prime.....)

OK, this one has me stumped...I have a 93 F150, 302 with the E4OD. I know the transmission needs to be rebuilt (probably a bad pump). When I put it in reverse, the engine will start to bog down and will die unless I put it back into park or neutral.
If the engine does die, the fuel pump does not prime with the key "on" and the engine obviously will not start. If I let the truck sit for about an hour, the fuel pump primes like it should and the engine starts right up. The fuel pump shut-off does not trip and all fuses are good.

I have a 2001 f350 v10 that has been giving me fits. has 88000 miles. cranks and starts when cold or fuel pressure is below 40 psi. SES light will flash when it stalls and fuel pressure goes from 30 while running to 40 and the fuel pump runs continuously when this happens and truck will not start. replaced crank sensor and fuel pump was changed about two months ago. if I relieve fuel pressure it will start and run for short time then stall and fuel pump stays on. all fuses are good. I am at a loss.

We've had two problems within the last week with our 2002 Sport Trac (4.0l SOHC engine w/167,xxx miles). They may be unrelated, but I suspect there's good change they are. Both incidents happened while my 16 yo daughter was driving, so there's only very limited info on what happens. Both times, when I get there, it starts and runs fine. There is no CEL.
The first time it apparently stalled as she neared her destination after driving only about 2-3 miles at 35 mph or less after a cold start. She was slowing to pull into a parking lot and reported the dash lit up with warning lights, no power steering assist and no power brakes and no power from the engine. When I arrived it started and ran normally. She had fulled up the day before after two days of heavy rain, so I suspected water in the gas. I drove it more than 200 miles within the next 24 hours under a variety of conditions and filled up at a different station. I experienced no problem what-so-ever, and didn't bother adding any dry gas.
Then 5 days later (still on my fill-up) when she tried starting it after sitting all day, she reported the engine started but ran rough before stalling and never idled normally.
Doesn't the fact there's no CEL eliminate a lot of the upstream part of the control system......like sensors and actuators? This leaves things like the downstream parts of the fuel and ignition systems. I.e. from the fuel tank / pump to the injectors and the downstream parts of the ignition system.
What are the possible culprits? Fuel pump, fuel pressure regulator, injectors, ignition module, spark plugs, and....... what else? (I'm not that familiar with what these engines have) And of the possibilities, what are the most likely causes.

ok, i just became the proud owner of a 71 dodge dart.. fuel pump was not working, and am converting to an electric (airtex e8016s) and am told i need a relay. airtex doesn't seem to have one, is there another i can use? fairly new at this sort of thing, but have fixed a 72 honda motorbike, so not afraid of engines or whatnot.

I have a 95 F150 4x4 reg cab long box with a 302 V8 and dual tanks... I was driving around yesterday when my truck started to lung and then the motor stalled... when I stopped moving I tried starting the truck and it started with no problem, so as i kept on my way, about 5 minutes later the same thing happened and it stalled again, (I have an automatic by the way). but this time before it stopped moving i pump the gas a few times and it fired back up and then stalled again... i switched from my front take to by back maybe thinking it could me my fuel pump in the tank but it did the same thing again about same time later... Would it be my fuel filter on the frame (like in line fuel filter) or why is it doing that? its EFI by the way.

I have a 1988 Ford F-250 Lariat, 7.5L 460, four-wheel drive. I have two fuel tanks on it, and I've been having a really annoying, obnoxious problem with it lately. After running it for a while, I noticed that I keep losing fuel pressure, and the truck stalls. When I try to start it, it does nothing but roll over. It just won't start. I've changed the fuel filter, I know both fuel pumps are working (I turn over the key, I can hear front, back, and high pressure pump attached to the left side frame rail kick in.) It's Fuel Injected, not EFI, hence that third pump. The problem happens a lot, and it's random. I could drive for 100 miles, stop to get something to eat, come out, and it won't start.
I thought maybe it was the fuel pressure regulator, but I don't think that's the case because it still runs. I would assume that if the regulator was bad, it wouldn't run at all. I also thought that maybe it was the relay, but according to some mechanics I spoke too, if I can hear the pumps kick in when I turn the key over, then the relay is fine. The only thing I could think of is that it might be the fuel selector switch. Maybe it's going bad, shorting out or something. When I flip the switch though, it switches between fuel tanks, and the gauge reads how much fuel is in it from the sending unit.
There's a schrader-type valve up by the fuel injectors. When I push it in, it barely squirts any fuel out, if at all, so I know the pressure is low. When I push it in on a good day, it sprays out like a water fountain. Just tried starting it again - no good. Pushed on the valve, it spurted out some fuel pretty well, but still won't start. Occasionally tries to, but ultimately won't. I know the spark is good, checked the plugs/distributor cap. Can't get the sucker to start.

I have recently purchased a 2012 facelift Tiguan diesel and it has a running fault. When starting the engine, 50% of the time it starts fine, 50% of the time it starts with a "misfire" and sputters for a short while (5-6 seconds) then stalls. If you Rev it a bit while it is sputtering then it clears the sputter and doesn't stall. It doesn't matter if it's hot or cold. Once it's running fine then the misfire never returns until you shut off the engine and then try to restart. The start stop also fails to cut in and I'm wondering if this could be linked. It had a new battery and alternator fitted a few months ago but a non start stop battery was fitted. This has now been changed for the correct battery but both problems still persist.

2012 SEL... Experiencing High Idle (1000 rpms) when the AC is ON. When I power the AC system OFF... the idle comes down to 700-800rpms. Then I power the AC back ON and it stays for the rest of my trip. Restart the car, and it's back to 1000 rpms with the AC on.

I have a 2005 Camry SE V6 with 73000k I just got it out of the body shop yesterday and everything seemed fine. i started the car up a short time ago and it stalled out when attempted to drive away. its idling at 400 rpms? I feel that the guys at the shop disconnected something.

I got my Touareg 2 months ago, and has been nothing but trouble. I also own a 1997 E39 BMW 528i, and I have never had so much problems with it in 8 years as with the VW in 2 months. Just plain terrible. There is now a strange problem, and it looks like the local service could not localise it properly.
My engine stalls at random. It usually happens at low RPMs, at a red light stop, etc. The engine usually goes bananas, the revs going up and down, and it looks like its choking. Sometimes switching to N and then pressing the revs up a few times works, but not always.
Sometimes the EPC and the triangle (exclamation mark) lights come up, but not always. It happened to me, that the engine just plain stopped.
It even happened to me when I was going slow down the hill in front of my house!!!
Can you imagine, initially I was firing up the engine with the button, having the key in my pocket.. And when the engine stalled, I lost all the servos, and the steering wheel just LOCKED!!!
I mean this is really serious. Since this happened twice, I am always using the key in its place... The local service just changed some electronics which supposedly monitor the engine RPM. It did not work...

It could happen once a month or 3 times a day. No pattern and never the first time I start my car for the day. But I will be running errands, park the tiguan, run into a store for 5, 15 or 30 minutes and when I get back in my car and start it up and go, it dies when shifting from 1st to 2nd. I know how to drive stick. This doesn't happen every time. I have called/taken it to the dealer 5 times and they have no clue because it never happens with them and I cannot predict when it will happen again. Also, on occasions, when i start my car, halfway through the day, the engine will idle really rough then the RPM's will spike and the car gives itself gas and my foot is definitely on the brake. These little issues are starting to piss me off, especially since the dealer just shrugs its shoulders.

Just got the Tiguan SE- love it! We have had it for about 3 weeks. I noticed sometimes while applying the brakes, the RPM's will go up as I am slowing down. I know the car has to move between gears when slowing down or speeding up, but it almost as if it gets "stuck" in a gear when the car is slowing down. Any thoughts, input? We don't drive fast, we apply the brakes and gas slowly to ease the car in. This just seems odd as my past car (2005 Maza 3) did not do this. I am new the VW family so maybe I am just not used this.

I have my aux fuel tank pump hooked to upfitter 3. It has worked perfectly until this week. I started to transfer fuel and the aux fuel gauge and fuel pump both quit. The led on upfitter switch 3 still illuminates, but no fuel pump. I found fuse 9 on passengers kick panel is for upfitter 3. The fuse was good. Is there another fuse somewhere for the circuit I've missed? I can trouble shoot the wiring if necessary, but it's tough to do all behind the left side underbed box and not easy to get to. I've missed something simple before I go further????

This van has had a couple of fuel pumps, no surprise there, and i need to look through my paperwork and find out how many miles the current one has on it, but it has the STRANGEST habit I've ever had on any vehicle. Starts fine, runs fine, no fuel pump noise when van is running, and when you turn it off, the fuel pump creeks on and off for several minutes.
I mean a strange creaking noise almost like a shorted electrical device or a vehicle's brakes when you park it on a hill and the breaks creak as it settles into place. I'm probably doing a lousy job of describing this but i don't know how else to describe it!
ALSO, if you lay under the van and wait til it stops creaking, you can tap the bottom of the tank and it will creak for a few more seconds. You can tap repeatedly and make it creak more. Is it about to explode? Can i trust it on a road trip?
