Hello. I am new here but I need help with a starting issue. We have a 1998 LMTV and the speedometer and volt gage went out while driving. Once we stopped the vehicle would power up with the switch but it would not turn over to start. We reset breaker CB77 (engine/gages). It fired right up. The next day the same thing happened. Speedo and volt gage went out and it wouldn’t start after turning it off. Does anyone have any suggestions? We are in northeast wisconsin if anyone can help locally. Thanks in advance!

Sounds like you have an intermittent short... Those are not easy to find. Get the TM and look at the wiring diagram. Does CB77 trip when you hit a bump? Best to use a multi meter and look for a short...

There are a bunch of wires that chafe on the gas pedal rod. Pull your dash and inspect.
