gas gauge quit working....

[banker099]

well a few days ago i did somethin dumb and took my neg battery cable off and my key was on.
when i put the battery cable back on and the gas gauge is stuck on ''E''
So today i changed the sending unit in the tank today and that didnt fix it, so i swapped gauge clusters thinkin the stepper motor on the gas gauge went out but that wasnt it either...now im out of ideas...HELP

Wiring issue.

At least you have a lift.

Fuse/relay?

[banker099]

Is there a fuse for the gas gauge? I checked alot of fuses and found nothin....also swapped the drl relay and the fuel relay and still nothin


Thanks for the suggestions lemme know if yall think of anything else

Is the gas gauge controlled by the PCM???

I believe it is. You pop'd something.

So you changed the fuel sending unit?

Gauge cluster?

Since you did both of those already, its going to be either a loose ground or some fuse / relay is dead. (IMO)

[GasGuzzler]

No fuse or relay. Gauge is commanded by PCM.

Wiring issue as stated before. Only other possible is a bad "new" part.

had the same problem. never got it fixed and it drove me crazy

If it's controlled by the pcm, maybe you sent a voltage spike through the wiring for the gauge into the pcm and toasted it. Find and check the wires to the pcm, and see if they're doing what they're supposed to be doing?

yep changed the sending unit and the gauge cluster...im thinking it is a fuse i missed or a pcm problem

could be a bad new part, i dont think its a wiring problems since it was working fine before i disconnected the battery

i got a buddy with an 02 pcm ill stick it in and see if it fixes it....ill keep yall posted and thanks again for the help!
