Gas gauge fuse

This is for "general" electrical discussions. Audio, security, remote start, and power accessories should go here, since they don't seem to fit anywhere else. Not for diesel-specific (like glow systems), or gasoline-specific (like ignition systems) topics.

Gas gauge fuse

Postby Vanjinxs666 » Sun Feb 05, 2017 10:26 am

Hey everyone, my fuel gauge isn't working on my 85 pup. I was wondering where the fuses were located for the gauge? Behind the gauge cluster? thanks in advance!

Does it work sometimes? Or not worked in a long time? Symptoms before it quit working? Anything else not working also?
I don't believe there's a fuse, but you could check the little fuse block under the hood. Pull out the fuses, if they look good ,clean them up and reinstall. Smear some wd40 on the blades.

If that doesn't work, try to find the wire that goes to the fuel tank sender. If you can manage to ground it out against the body, the gauge should go to full. Maybe the wire came off or broken under the truck

The sender's in the tanks sometimes go bad. When grounding out the wire and the needle goes to full means the sender probably bad.

Well, i bought the truck and it hasn't worked for me ever. It has a new motor in it and a new aftermarket fuse box and new fuses. I'll check the wire near the tank and go from there.

Based on your post from Part, your sender may be bad. I don't think they're available new. Jerry LEMOND mentioned once there was someone he knew that was taking old ones and rebuilding them somehow. Check with Jlemond.

Surprsingly autozone said they can get me a new one, but I haven't removed it yet. Going to remove it tomorrow and make sure it isn't the float.

Be sure they're not looking up an 88-95 sender
