Re: Fuel gauge issue
You said there was as Air Ride Switch that shorted out.You should check all the fuses with a test light.
I added a radio to my truck recently. After passing the wires back and forth my gauge went to full. The gauge was un-plugged. That would be the same as no power or a blown fuse. I plugged it back in and it was back to normal. |

Re: Fuel gauge issue
Ok so I unplugged the plug at the gauge and it stays empty. Hook it back up and unhook sending wire plug at main harness and gauge goes to full.... Here’s the weird part! I drove it a bit yesterday and it worked for a few seconds then went back to full again. I’ve checked and all my grounds are good, not corroded or broken. What should I look for next? Sending unit or gauge?

Re: Fuel gauge issue
If you disconnected the sending unit from the system, then you have a short/ground somewhere. Grounding the sender wire will make the gauge go to full.

Re: Fuel gauge issue
I just unplugged the sending wire that feeds the gauge and it still went full but unplugging the two prong on the gauge it went dead empty. I can’t even get to my tank sending unit without dropping the tank....
