2013 f550
While looking for a wiring issue under my truck with a power probe , I probed the fuel sender Wire and now I don’t have a working fuel gauge. I’ve checked all the fuses and I can’t find one blown . Can anyone help me out ?
it’s a 2013 F550 6.7 4x4

Welcome to the site.
Happen to know which color/tracer you back probed?
Put the IPC into test mode and see if the fuel sweeps.
To enter test mode, press and hold the message center RESET button. Then, turn the ignition switch to the RUN position and continue to hold the RESET button until the display indicates ENGINEERING TEST MODE, usually within 3-5 seconds. Next, press the RESET button once to advance through 'each' stage of the self-test. Stop at GAUGE.. All gauges will sweep as would the fuel and it would stop/set at the current fuel level. Sweep and reset?
If the gauges sweep,, you might with a meter, check the YE/VT for a signal/ref voltage input to the level sensor from the IPC.. Missing?
You may need to have to have the IPC checked for out of range code/s (Short to ground,, Open/short to voltage) if a fault is found..

A suggestion for what it is worth,
Checking anything on a vehicle with computers using a Power Probe is NOT recommended.There are circuits that if full voltage is applied ,they can be rendered inoperative AND expensive to replace.
If you can isolate the circuit from everything else you might be able to check for continuity. A test lite is good for confirming power present, but applying power to ANYTHING is asking for trouble..
