The fuel gauge on my 2000 Blazer is flipping from empty to full. (Even as I drive down the road it moves.) And nothing in between. The fuel pump was replaced about a year and a half ago. I've been told the fuel pump controls the fuel gauge. So I'm wondering if there could be a loose contection or if this is a sign the pump will go bad again.
View 6 RepliesI have a 2000 Silverado Z71 with the fuel gauge swinging from empty to full and all in between. I have heard of others doing this. I guess maybe its time for a new fuel module. It's been doing this for a couple of years, just keep putting it off. Is it easier to move the bed back or drop the gas tank? Also I have developed hard starting problems here lately, It having too crank extra long before it starts up. Could this be a sign the fuel pump is getting ready to go out.
View 8 RepliesWhen my fuel gauge gets to 3/4s full it stops working and goes to empty. My range display also goes off. When I refill it works again until it reaches the same point.
View 5 RepliesFull 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.

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
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?
I have a 2003 Buick LeSabre Limited, and everything was going fine with it till recently. The Fuel gauge started to go haywire as in the needle would go to full, then go back down to a Quarter, then back to 3/4, then drop all the way down to Empty, this is still occurring. At first I believed it to be the fuel level sensor, but then I started to notice something else.
A warning message came on stating that the oil level was too low, but when I checked the oil level it was fine, and last night when I was driving with the air conditioner on, I hit a bump and the air conditioner stopped working. I pushed the off button, and was successfully able to make the air conditioner to come back on with out having to restart the car.
The horn has also started to go in and out, and I do not know if they are all linked together by a type of computer or if they are separate.
My car is still at the dealer after having the recall done because they can't get the fuel gauge to start working after they performed the recall. But the gauge had nothing to do with the recall you might say. Correct. But prior to the recall being done the gauge was acting funny. Going from full to empty to 3/4 back to the current level.
I told the dealer about this and they looked into it as they were doing the recall. Now they said they replaced the fuel level sender unit, certain wiring connections but to no avail they still can't get it to work. So my question is, what is the type of Gremlin that could be causing this?

Bought the car six months ago.Found out 2 weeks later we couldn't put gas in it. Dealership refused to fix it because we bought as is. So we managed to find one gas station in a 20 Mile radius that we could put gas in it.It takes around 10 minutes to put half a tank in. Shortly after that the gas gauge started to fluctuate from full to empty. And the check engine finally came on. Had the the check engine light checked.Fuel level sensor A was faulty. Took it to a local Goodyear in stead of the dealer ship. The sensors were 119.00 a piece and the labor was 145.00 to replace both. Had both replaced .Fuel gauge is working correctly now. But still having issue putting gas in car.
Ok so the fuel gauge says empty and the low fuel light stays on even though the tank is full. I'm assuming its either the gauges or the sending unit. If it is the sending unit where is it located on this car?
View 4 Repliesfuel gauge does what it wants? It goes down to half way then goes back to full or sometimes even empty. Not a big deal for me because I have gotten used to it. But I would hate to have my wife in here and she thinks it's good and run out.
View 14 RepliesMy fuel gauge acted pretty weird today. When I left my house today it was just above half a tank. I was sitting in traffic quite a bit and then looked down and it was below the e. I knew it wasn't empty so I kept going. Got to work. Went for lunch and it said full drove about 5 mins to eat and it went down to half a tank. What's going on? I am thinking of the fuel sender or wiring?
View 3 RepliesI have an 03 f350 4x4 cc long bed and I seem to be having a problem with my fuel gauge. It doesn't show the true amount of what's in the tank and because of that I have run out of fuel a few times.
sometimes when I'm driving the light will come on and the gauge will drop all the way to empty then a little later it will go to almost full even with only putting 10 gals in the tank.
Any fix for this or do I need to replace the sending unit?
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 recently had some issues getting my 2000 Blazer LS started. It would act as though the battery was dying. But if I let it set a few moments, it would start right up. Then a couple days later, I needed a jump start to get it going. I took it to my local Auto Zone to have the alternator tested because the battery was only 3 years old. (It was a 5 year battery.)
They determined that it was the battery. So I went to Walmart and bought a 700 CCA battery. And today the gauge is fluctuating again.... Considering it is cold and snowing here, heat, wipers, and rear defrost tend to be essential. But if I try to run all of them, the gauge dumps. And causes everything to bog down. I do not have any aftermarket electronics installed in the truck. And until last Thursday, this was not an issue.
2004, 3 door Accent, 150K miles. This has been going on for many summers now (had an idea when driving from work). Well when I got home from work, gauge still read E, turned the car off, then back to ACC, still read E.
Opened the fuel cap, didn't hear any hissing noise or any indication that there was alot of pressure build up, put cap back on, turned to ACC, and gauge read normal.
So after a long story my question is this, is there a pressure regulator that when it over pressures, lets it vent, and what is it called and where is it located? I am thinking that regulator might be stuck closed.
I have a 2004 Hyundai accent hatchback with 225000km. The first time I drove it for over an hour, 1 trip no stops, the fuel gauge dropped to empty while there was 3/4 of a tank. The 2nd time I drove over an 1 the fuel gauge dropped again and the gas light came on (again around 3/4 of a tank). My mechanic said until it does it consistently he can't diagnose so I let it go.
More recently, driving it to and from work 5 days, plus some extra city driving, I used 1/4 tank the full week. Today I picked up 4 winter tires and bringing them home (approximately the same distance as my work) I used 1/4 tank right there. I understand it is weighed down, but could it really be that much? What is causing the fuel jumps and gauge jumps? I've already had the float replaced.
My gas gauge is intermittent. most of the time it reads right, but like 30% of the time it shows empty regardless of how full the tank is. What would cause this?
View 6 RepliesI have a Chevy 2006 Malibu LT V6 and when i first got the car a year ago I had no problems. After a few months, I would fill up the tank up completely and then drive it around and stop at a stop light. The gas meter would drop from Full to Empty with the light coming on then reset itself. It happened sparingly so I thought nothing of it. Now just a few days ago I filled the tank up and now the gauge is staying at Full when I know for a fact that I do not have a full tank. Whenever I turn on the car, the gas gauge needle jumps from full to empty to half to full to quarter until ending at full. Lately, I've been trying to go off the fuel mileage on my radio but with that resetting to what my fuel gauge says I'm getting fearful of running out of gas.
View 10 RepliesI have a 2004 F150 XLT 5.4 L 79,000 miles. Yesterday i was driving home turned a corner and the low fuel light came on and the fuel gauge is well below empty. I had approx 1/2 tank of fuel when it happened. I have since filled tank all the way but the gauge will not move and low fuel light stays on. Everything else is working fine! I have never run the truck low enough on fuel to make the dummy light come on.....
