LPG Lock Off OORL (Out Of Range Low)
has anyone disconnected the LPG lock-off with the truck running? does the LPG lock-off wires have a break from vibration that has broken the wires inside the insulation? (pull/tug the wires and see if there is any stretch to the insulation, which would indicate a broken metal wire section, and replace that section of wire, I see this most often right near the connection to the LPG lock-off on the truck harness side.
