The rear strap that holds the gasoline tank in my vehicle broke due to corrosion of the strap. The tank stayed inplace until I could drive to the dealer to have it replaced. The dealer was not concerned and ordered the part and schedueld to replace it in a week.
1999 GMC Sierra fuel system complaints
Page 2 of 2: complaints 11 to 26 of 26, newest first, as owners wrote them.
Dt: the contact stated that the fuel gauge indicator iwasnot working correctly. When the fuel tank was filled up the gauge will move to empty, and the low fuel light will come on. After driving the vehicle for a while the gauge will move to full. But with continued driving the gauge will drop down to empty, and the fuel light will come on again. The service dealer stated that the sensor needed to be replaced. The contact had not replaced the sensor.
Gas tank gauge works once in a while. Our mechanic said it was probably due to moisture. Also, the rear differential cover is either cracking or rusting through. I put a new gasket on it and the next day it was leaking again but not at the gasket. About 1/3 up from the bottom, you can see where fluid is leaking through the cover. I called 2 dealers (1 chevrolet, 1 gmc). They both gave me numbers to other dealers (1 in pa., 1 in ia., 1 in upper mi.). The two out of state dealers told me that the part was for a customer and would not sell it. The one in mi. Also said that, in addition to "that must be a popular part, because I've had every dealer in the country call me." is this part a defective piece?
Truck running sluggish. Difficult to start at times. Hooked up to computer a couple times and showed different sensors bad at different times. Driving to work on 7/7/2005 vehicle suddenly shuts down, able to pull into a resturant parking lot. Problem : fuel pressure regulator clogged ( this is a vaccum line no gas should go through it) causing gas to flow at 60 pounds fuel pressure into the intake manifold causing a fire. Because of this the manifold burned a big hole where #4 cylinder would be located. This happened while I was driving 55 MPH down the road & was possibly still burning while I waited in my vehilcle to be picked up. I believe this is a dangerous & should be looked at. My girlfriends nephew found the problem & replaced the intake manifold & fuel pressure regulator. While working on my 99 gmc sierra her brother who drives a 2000 gmc sierra describes the same problems I was experiencing & promptly brings over his truck. Upon looking at his fuel pressure regulator it also was full of gas ! His was found earlier without resulting in fire & his fuel pressure regulator was replaced. I contacted gmc & they have given me a hard time, because they wanted me to take it to a gmc garage, I was not going to pay to have it towed there . But plan on stopping there monday 7/18/05 to show them the parts ( I have the fuel pressure regulator & the intake manifold with the hole burnt through)
Throttle body plate sticks, having to surge engine to unstick throttle
Fuel gauge sending unit failed @ 57k miles. Called gm. No satisfaction. Cost to replace, with labor, is $700!!..for a toilet bowl float??!! Sheesh! Haven't fixed. Replacement cost is outrageous and it shouldn't have failed to begin with, especially not that early.
The fuel gauge located on the dashboard malfunctioned. The lever fluctuateed between full and empty. The accurate amount of fuel in the tank was unknown. To correct this failure the fuel level sensor has to be replaced. This is a common failure with these vehicles.
Faulty braking system engine noise muffler replace instrument panel fault tire wear transmission automatic shifting rearend noise
Fuel pump will over heat and than short out. Exhaust always rattles engine knocks cat. Converters went out digital display stopped working
While on a trip gas gauge malfunctioned. The fuel gauge remained on 3/4 while the mileage was 335. When filling the tank it showed full after 4 gallons were delivered. The problem continued thereafter till present. The only way to know the fuel level is by the tripometer and guess work.
The gas tank leaked.
Consumer noticed a gas leak. Had vehicle serviced and was informed that carbon monoxide constantly builds up and seals the gas tank, causing a leak at the seam of the tank. Ts *tt *jb.
This is the second failure of the fuel pump. The first was slow to fail, this one was sudden and caused to vehicle to slow abruptly. Had we not been close to the offramp, who knows the danger. The antilock breaks have also failed as well as another engine electrical component that caused the engine to stop running.
Gas filter is not working properly, filter is not allowing a lot of gas to flow through because when starting vehicle there is some noise that comes from the engine. Contacted dealer, and dealer was the one who stated that was the problem with vehicle.
Fuel pump is not working properly, and the vehicle is shutting off. Contacted dealer, and the dealer was not willing to do anything.
Intermittently engine check and oil lights will illuminate while the vehicle is being driven. Dealer has been notified.
