There are a few possible things. easiest to hardest, check your spark plugs for wear and gap. if its not the plugs it could be water in fuel system freezing. in colder enviorments it is always best to get highest octane fuel available because it contains less water. try adding an octane booster or fuel stabalizer when fueling up. also fuel filter may be at the end of its lifespan, it would take more cranking to suck the fuel through it if it is clogged.

SOURCE: fuel gauge stuck on half full

I can tell you almost for certain your fuel level sending unit is bad, I have been able to fix them though. It requires removing the gas tank and then the fuel pump. You can if your inclined, bend the brushes on the small circuit board over more so they will make better contact on to it. Other wise its a new fuel pump assembly, check all plugs and wiring by unpluging and repluging them to insure no bad connect. It is possible it could be the guage itself, but in thirty years of fixing cars never had a bad guage

SOURCE: gmc jimmy 1999, fuel gauge reading empty, even

the sending unit inside the tank has a open circuit that will not complete the signal to the dash gage. The tank will have to be dropped to replace this. The fuel pump is also a part of the sending unit. The part is not very cheap neither

SOURCE: gas gauge is not working, temp gauge is not

Try unhooking one of the battery cables and leave it off for at least 20 minutes. When you hook it back up the

computers should re-boot. That has solved problems for me with heater, interior lites, power windows, AC, day

time running lites, power mirrors, fast idle, rough or slow shifting, CD player, and wipers on GM autos and S-10

PU and Dodge trucks. None of the switches are connected to the device they control anymore. The switch tells

the computer to open the window and the computer sends a signal to the window motor. When the computer gets

confused strange things will happen or not happen. Things like one headlight stays off etc. I actually had to do

it twice on my Bonneville because the first time the AC blower would only work in low and medium. After the

second re-boot, everything was fine. Of course you may have to re-set your radio stations.

Starter or ingition switch problem. Let me guess, you live in a cold region? If yes, then I'm betting money on the starter. The cold does a number on starters. The colder it gets the more likely they go out. Lol, happened to my friends truck Tuesday and mine this morning. That's what we get for living in -10 degree weather right?

chevy and gmc trucks have an on going problem with this,turn the key on,and get a rubber mallot or a hammer and hit the bottom of the fuel tank a couple of times,this will unstick something in the fuel pump/sending unit.

96 jimmy shuts off while running and will turn back on, changed control module and the throttle body and MAF sensor. told by dealer to change this and problem would be fixed, problem not fixed.


i have had problems with the fuel pump relays heating up and loosing contact. it will not trigger a code and the only way to track it is to attatch a fuel pressure gauge to the system and wait for it to die. chances are you will see the pressure drop to 0 psi.

the fuel pressure if leaking could cause this the regulator is located under the intake plenum but you should smell gas .if you dont then most likely the pump is bad ,the pump will come on for 2 seconds when the key is on then go off it will not stay on with just the key on only when you crank it will it .so have your fuel pressure checked with a gauge.

I had the very same problem with my 97' jimmy. I finally replace the ignition wiring harness. That controls the electrical going to the dash. Blinkers, gauges, fuel pump, I also replaced the Key switch just in case. Started right up all gauges work,blinkers everything.
