Prius (Gen 2) :: Tank Is Not Full But Fuel Pump Keeps Clicking Off
Nov 30, 2014
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 had less than half a tank and went to fill up before a long drive. At the gas station, the pump wouldn't let me put any gas in the tank , it kept clicking stop. I gave up and was going to try again later, however when I turned my car back on, it said I had a full tank all of a sudden.
The gauge on my dashboard isn't going down at the right speed either.

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 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?

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

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 just picked up a gen II prius last week. it came with 70k miles and almost a full tank, i think 2 'pips' were gone. since I got my car I've driven a total of 135 miles and already my fuel level went down to 2 pips.
I needed to fill up my tank, so on my way home today I went to a gas station filled up with 87 octane fuel. The fuel pump automatically stopped after about 5 gallons. I had less than a quarter tank, therefore my car should not be full with 5 gallons, according to the manual the tank is just shy of 12 gal. I know my prius has the shrinking bladder or whatever since its a g II, but this is a little extreme. According to my car, I've been getting an average of 35 mpg.

I just bought a 2014 Prius- Pkg. 2 car. I had an '06 & an '08 Prius and kept the tire pressure @ 44 Lb.s for maximum mileage. I always fill my tank to the top well after the pump clicks off.
1) The dlr. told me I will only get an accurate MPG by not filling the tank after the pump clicks off. He claims the computer doesn't read the extra 1-2 gallons and that is causing me to get about 35 MPG even though the trip meter says 50 MPG.
2) The dlr. told me not to run my tires @ 44 lbs. Said it is a safety issue. I've been doing 44 lbs. since 2006 with great mileage and no safety issues.
Am I wrong for filling my tank to the top? My Prius has just over 600 miles today.

I have a 2006 Prius, 149,000 miles. The gas gauge has just become stuck on 2 bars. I discovered this after attempting to fill the gas tank. I was unable to pump the gas into the tank. The pump kept clicking off immediately. I was able to slowly put about 3.5 gals of gas in the tank, but very slowly. I also tried to add gas from a gas can, and the same problem occurred: the gas would go in very slowly. I have never had the fueling problem where the pump repeatedly clicks off. I tried several gas stations that had pumps that worked for me in the past, and didn't have any luck. The fuel gauge failure and the gas pumping problem have appeared simultaneously.

I was filling up the Phaeton tonight when the gas pump malfunctioned. Instead of shutting off when the tank was full, it just kept on pumping until gas came spewing out of the tank. The side of the car (and my best pair of pants) got drenched in gasoline. I immediately went home, threw my clothes in the laundry, took a long shower, washed and waxed the car, and cleaned the seats with leather conditioner for good measure. The car still smells of gasoline, but not so badly now.
My question is this: Is there harm in filling the tank completely to the brim? Because my tank is now as full as it possibly can be. Is there anything I should do before I drive it again?

My car is a 2003 Hyundai accent . When getting gas, the gas pump often shuts off several times( almost every $0.50 of gas) well before my gas tank is full. Also, I have to fill the tank VERY SLOWLY to prevent spills and it takes a long time to fill up the tank. After Im done the car takes gives a bit of problem to start. Could it be the fuel filter?

When I fill up gas at the pump, the pump continually cuts off as if the tank is full. I spend about 10 minutes at the gas station filling up the tank, and I can never tell if the tank is full or if the hose is just cutting off. The car mechanic told me the replacement vent line cost $200 to $300 to replace (with labor). Is there any cheaper solution?

I found the one way valve at the filler neck that seems to be installed backwards and turn it around, now fuel flows much faster and no clicking mid fueling.

It was pointing in the opposite direction as it is now.

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?

A couple of weeks ago I went to the gas station and was unable to fill the tank as the pump kept clicking off. I assumed it was a problem with the pump. Because I was in a hurry, I left and stopped at another station later in the day. I was able to pump 11 gallons into the tank, but the gauge still registered near empty. The local dealer told us it was a problem with the gauge and replaced a sending unit. This appeared to fix the problem, but yesterday morning when I stopped at the gas station, I was only able to pump 2 gallons because the pump kept clicking off. The gauge reads about 1/4 tank.

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 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.
