mcratchet1 Posted 10 hours ago Share Posted 10 hours ago Hello, I have a strange issue with my 2013 Mack mru with mp7 engine. I was pumping in the rain and truck try to kill four different times. Rained stop no problems came back to shop. Getting a pid94 fmi 7 code. Pulled truck up and degreased around fuel filter area. Try to start truck it crank and ran about 1 minute and stalled. Would not start up. I took my blower and dried the whole drivers side engine and then it started right up. So is there a sensor issue or wiring intruding water that would stop truck from starting. Just trying to get an idea where to start looking. Thanks Quote Link to comment https://www.bigmacktrucks.com/topic/75731-rain-shut-truck-off/ Share on other sites More sharing options...
