GTI 337/20th Anniversary :: Fuel Cutoff When Tank Gets Less Than 1/3 Full
Jul 31, 2011
I am the original owner of a 337 with 292,800 miles, that's correct. I recently have had a fuel cutoff problem when the fuel tank gets less than 1/3 full. So I replaced the fuel pump and fuel filter thinking that would solve the problem. It still stalls with a low fuel tank. It runs fine with more than a 1/2 tank. I have a Vagcom and no issues there.
Mystified at what could be the cause. Possibly fuel pressure regulator or vacuum line, is there a check valve somewhere in the fuel system that could be sticking, or what about an issue with the EVAP system? By the way this car still looks great, has been to the track many times as well as autocrossed, and still has the original clutch. Way to go VW. My race car is a spec miata.

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?

I don't think this is normal since my 01 2004.5 GLi go all the way... Note that i took this picture right after i "full" fueled the car (Just drove 2.3miles)...

Happened on my mk6 now on the 20th! When I go to hit the switch for the gas tank release it is completely silent. Could that be the module? Half a tank left so not to worried about bringing it somewhere.

Sometimes while driving if i accelerate the car fully the rpms will accelerate way to fast (at least 2x faster than usual) without picking up much speed at all. I can tell that the car is not going to full boost. The problem is the worst in 5th and 6th gear (when the car is relying more on boost im guessing?) and will happen one day and be perfectly fine the next. I just had the car checked for a boost leak about 3 weeks ago so i dont think its that. The car is chipped with uni stage 1+ (20psi) and has a full 3 inch turboback.

I am running the GIAC X+ 93 octane tune with a cold air intake and when i hit full boost it fluctuates from 20 to 15 through out the gear. i am guessing its because of my stock dv. im looking in buying the eurojet dv.

This has happened to me 4 times now in the 7 years I've owned my car. It happened so infrequently I thought the problem was the pump's sensor was not working properly. However now it's happened twice the last two times I've tried to fill up. On Friday my son was supposed to fill the car and could only get 1 gallon in and the fuel pump kept clicking off as if the car is full of gas. The bars never moved and I thought the problem was the pump. Then today, Sunday 2 days later, I decided to go ahead and fill it up. I have 250 miles to drive and want a full tank of gas. The tank shows 3 bars. I started fueling and it clicked off at 1 gallon. So I pulled the pump trigger again and tried to force more fuel in and it stopped and wouldn't add anymore than 1.7 gallons.
So now I have a long drive tomorrow and I can't figure out why the pump is clicking off as if the tank is full yet it can't be because I drove 250 miles since my son tried to put gas in and it's showing I have 3 bars.

I generally average north of 50mpg on a regular basis. Yet, my cruising range is always somewhere around 300~ miles for a full tank.

So I'm now on my second week with this 2012 Prius and still trying to learn how to roll in it.
I filled up my very first tank yesterday (dealer gave me a full tank when I bought it) and the miles remaining display said 424 miles after I filled up. Does it display 424 on all Priuses by default?
The first tank gave me right around that many miles before I filled up - the miles remaining display said I had 9 miles left so I got too scared to see if I could go farther. But when I filled it, I only filled just under 10 gallons - does that mean there's more miles for me to drive, despite that remaining miles meter?
And...am I getting pretty bad fuel economy?

Full tank and the gauge reads empty. Has happened to me a few times. Occurs after a fillup and disappears after the car is left to sit for a while off. I would hate for this to happen on a long drive. Dealer hasn't been able to duplicate the issue. Am wondering if this might be related to the hiccup in some way. Also, am wondering if this is a fuse issue.

The computer apparently calculates the fuel economy per trip (or a series of trips if the car is stopped less than 2 hours) but I don't know how to get it to display the fuel economy for the tank full. Normally I'd reset the computer upon refilling but since it calculates per trip it doesn't calculate per tank. Fortunately the fuel gauge seems to be pretty accurate and each mark is approx 1 gal so I can do a quick approximation but I'm used to having the car do the tankful calculation. BTW, I reset on MFA 1, I've never reset on MFA 2 and that doesn't show tankful economy either.

I'm new to the Gen 1.
All has been well in just over a month of driving the car and about 3300 miles logged. The 12v, Aux battery was dead from the car sitting on the lot for so long (I replaced with a new OEM Toyota 12v battery) After a week of the car experiencing dim headlights, and various other electronics
No codes or CEL though.
Now that the 12v battery has been replaced, the car runs exceptionally well, aside from an intermittent fuel gauge issue where it only reads full bars (completely full) if I let the tank get to empty (Flashing single bar) or close to that. If I fill the tank from s

I just bought my 2012 Elantra Limited from the dealer today . The fuel gauge showed about two bars, a quarter tank I estimated. However when I went to fuel it, the pump clicked off after about 1 gallon, indicating the tank was full.
That was odd so I just figured there was some air in the tank or in the hose, so I tried adding some more fuel. I got about a half gallon more added when it clicked off again. Well, I know you're not supposed to top off the tank so I tried to add more. Got about two gallons added when it clicked off. I stopped fueling at that point for fear of causing damage.
My fuel gauge now shows a little less than half full. How can that be? Is there something I can do to fix this?

I have a 2007 Santa Fe. If I fill the tank to full, or close to full I will have a fuel smell in the car until the tank runs under 3/4. If I keep it under 3/4 I usally do not get the smell in the car.
The dealer could not figure it out and I still have this issue. It seems the smell is more in the front of the cabin then the rear. It just could seem that way since the smell is very strong. I have to park the car with the windows open.
There are no fuel leaks, no fuel on the ground, no drips, and the no spillage when I filled the tank.

So yesterday I was driving home from work.. I know my tank was 3/4 full. All of a sudden, my low fuel light came on and my gas gauge needle went to empty.
The needle sits at E, but it still says about 20 miles till empty on the MFD. When I left the house this morning, it said 5miles till empty.. by the time I got to work, it said 20. Kinda odd..
I will hook up the vagcom when I get home tonight, any area I should scan for? or just a complete scan? There is no CEL error on the dash though. What I could look at to fix this?

Been driving for 3 days now for a total of about 100 miles from a full tank averaging 50 miles per gallon. I noticed the gauge still shows FULL. Not even a bar below or something. Is there anything wrong with my gauge?

I have a 2001 Chevy Silverado with the 4.8L V-8 engine. It acts like it is running out of gas ( the gas tank is over half full). The truck has sat for about 6 months in this condition without being started here in Sacramento, CA. I then replaced the fuel filter and for a few minutes it started and the engine ran fine (without actually driving it). A few days later I started it again and it now again acts like it has fuel starvation, it will rev up briefly then act like it is running out of fuel. I know the fuel pumps are the Achilles Heel of these trucks, but before I try changing it I was wondering if there might perhaps be another problem such as the new fuel filter plugging up quickly or possibly an electrical problem. I've always heard these fuel pumps either work or they don't work, nothing in between. This problem is intermittent but big enough the truck is not driveable. Is there any way to get a good take on the problem before diving into the fuel pump replacement and hoping that solves the problem ?

Having trouble with the fuel level readings in their t-reg? When I fill mine up it shows as full but drops to 3/4 of a tank within 10 miles. Then it reads fine for about 300 or so miles and then drops to empty in about 20 or 30 miles. When I fill it back up it still has 6 or 7 gallons left. And yes, I am using 91 octane gas.

I have recently purchased a 2001 Accent GS which has the 1.6L DOHC engine and have done a big road trip in it which has created a problem. When I fill the fuel tank up it runs really rough, has no power, and stalls at idle unless I keep the revs up. I can also smell petrol very strongly in the car all the time, plus it's running really rich as I can smell fuel on the exhaust and the last symptom is the loss of power down low(due to running rich).
I was on my road trip so had no tools on me and got the local mechanic of a small town to do a few basic things (change spark plugs, leads, and fuel filter) but to no avail. It runs smoothly when it gets below the full line on the fuel level gauge so I just didn't fill it up completely to get the car home but it still runs really rich and doesn't have quite as much power.

I have an 02' Blazer 2Door 2WD 4.3L vortec. Great truck - very low miles. About a month ago the fuel pump went out. She was showing signs / not starting on the 1st/2nd try and finally wouldn't start. It's a 12 year old pump and I was also that guy trying to make til Friday on a quarter tank - so no complaints so far. I checked the relay and fuse, all good there - so I bought a new AC Delco and fuel filter. Drained and dropped the tank, cleaned and dried the tank and installed the new fuel filter. The pump came with a new pigtail - so I wired in the new pigtail, attached the hoses and re-attached the tank. Not bad for 6 hours of work ( first time - don't judge ). She fired right up and ran like a champ / about a week later I stopped and filled up the gas tank. Next day - no start / no whine from pump / 0 psi at the schrader valve.
Assuming it must be an electrical issue - I dropped the tank and tested the gray power wire / 12 volts. But to be thorough / in case I made a mistake / I stripped and re crimped all the connections, heat-sealed the sleeves and wrapped in all in electric tape. Tested the pump - she hummed like a kitty. Re-installed the tank and she fired up like a champ. Drove around a couple of days - stopped and filled the tank with gas. Same thing - wouldn't start right there at the pump. i poured fuel in the intake - she would start and run until the fuel burned up.
No hum from the pump. had it towed home ... again ... began to siphon my now full tank of fuel to drop it yet again. At about 1/2 way , I tried her and the pump primed and she started right away. For the past two weeks I have been unable to make it NOT WORK - but i am worried to go very far , less i be stranded again. on the gauge I get 60 with the key on and 56 running. With the engine off the pressure holds for quite a long time - well over an hour+. So what would cause a brand new AC Delco pump to not work only when the tank is full - then start working when some of the fuel is removed?

I have a 98 4 Runner the fuel light has come on, the fuel gauge itself is working fine. The low fuel indicator light stays on even on a full tank, would like to know if there is a reset button or is it attached to the fuel sending unit or is it a separate unit....
