gas gauge quit working....

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?

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)

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

No fuse or relay. Gauge is commanded by PCM.

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

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!
