Chevrolet Blazer Problem Report

Chevrolet Blazer Erratic Fuel Gauge Operation

(101 reports)

The fuel level sensor in the fuel tank may fail causing erratic fuel gauge operation. Our technicians tell us that on high mileage vehicles you may wish to replace the complete fuel pump module assembly if this condition occurs.

had the fuel pump replaced at 93000 miles and it is doing the same thing AGAIN! Chevy manufacture knows about the continual problems of the BLAZERS but REFUSES to do any type of RECALLS. We must unite in this cause because all of us owners will be subjected to these different and very costly I might add! problems if we don't do something now I hear about more and more problems about this blazer no matter what year you own. CHEVY needs to own up about it's problems that all chevy owners have not just the Blazer series and yes we have 3 Vehicles that are Chevy's LOL and this fuel gage is the same in all of ours but more predominately in the Blazer (my car go figure the one that does the most running around) other mom's and dad's know what I am talking about LOL. -
gas gauge goes from F to E and the low fuel light comes on and bounces back and forth -
fuel gauge is erratic, it's from E TO F. this should be a recall -
Erratic fuel gauge operation. "Service Engine Soon" light comes on because fuel level sensor is drawing too much voltage. -
when tank is about half guage will jump to f to e then stay at about 1/4 -
I have the same problem AA mini vans have like the VENTURE I have had three, the rotten stickin feul level gauge should be recalled it has never worked sinve 20,000 miles, NOBODY seems to care, some hints, as an electrical guy, it seems it could be due a wiring, crapper connector, maybe plug perhaps underneth vehical, FOor a while i could effect the gauge and bruing it "true" by BANGING ON THE GAUGE AT THE DASH OTHER TIMES WHEN I PURPOSELY HIT BIG SHARP BUMPS ESPECIALLY while backing up it would go back to true for sometimes days, cheys's input was ho hum, buy another car jackass, I am going to longer buy american because they arn';t americans any longer they are gov't run communists and completely irresponsible !

When the problem first started the gas gauge would fluctuate from full to empty very often. Now it stays above 3/4 of a tank at all times except when idling, then it goes all the way down to E and the low fuel light comes on. When you let hit the gas it goes back up to 3/4-full. -
Usually only happens when I put it in nuetral and have less than half a tank. -
Purchased 2004 Chevy Blazer LS, 2dr, 4wd on 07/30/11 from dealer with recorded 79,322 miles. Displayed current PA emissions and inspection stickers with dates 6/2012. Vehicle gas tank was filled immediately after purchase. Drove 75 miles after fill up. Next day, upon starting vehicle low fuel light came on. Drove vehicle about five miles and low fuel light went out. The gas gauge reading went from full to 3/4 tank to 1/2 tank back up to 3/4 tank, then continued to float until settling at about 1/2 tank. 4 days after purchase, 08/03/11, instrument panel gauge assembly replaced by independent mechanic, due to low fuel light on and faulty fuel gauge reading. 08/09/11 after market fuel pump assembly (indicating at least one prior issue) replaced with GM OEM fuel pump. Documented mileage on repair order, for both repairs, 79542 miles. Cost of instrument cluster, $285.00. Fuel pump assembly list price, $536.44. Total cost of repairs $1029.23 with labor included. -
fuel guage bounces at will from full to empty will stop momentarily then start bouncing again.very unreliable.also has heater flap door broken AGAIN!!!!! -
It isnt repaired yet can not relie on fuel gage must go by mileage -
replaced my fuel pump.the problem continues. -
I own a 2002 Chevy Blazer that has 100,000 miles on it,at around 60,000 miles i began experiencing a problem with the fuel gauge bouncing between empty and full the gauge would settle to the empty mark with about a half of a tank of fuel. i also noticed that when this condition would occur if i would shift from drive to park then back to drive the fuel gauge would would come of the empty mark and settle around the half tank mark. i have noticed that this is a common problem with the Chevy blazers and believe that Chevy should have realized by know that this is a common problem due to defective components and should stand behind their product and do whats right issue a recall and fix the problem -
Fuel level sensor would jump back and forth. Mechanic replaced the fuel pump and fixed the problem. -
no fuel level indicator most times -
The gage would show full after a gas fill up but would soon drop to showing no fuel and then it may jump up to show fuel. Then the gage would show no fuel even with half a tank. I will probably have to replace the entire fuel pump which contains the fuel level sending unit. -
My blazer reads full when you fill it up, and stays fairly accurate until you reach half a tank. it will go erratic, stopping at random positions. I notice the needle dances most when I shift to park, and it stops when I shift out, for a time. -
gas gauge goes from full to empty several times during a trip even when I know there's only a half tank left. -
Didn't fix it, but half a tank is my new empty level. I decided to worry about the things I can change instead :) I'm in Australia, so it sounded too expensive to fix -
how cant fix fuel level sensor. -
