2009 MP7 Granite shuts down


Recommended Posts

Truck goes down the road and then goes limp with no throttle response and sits at 600RPM until you pull over. Once on the side of the road and fully stopped it just shuts off and then fires right back up and good to go some more. Sometimes you get 5 minutes, sometimes 30 minutes. All battery cables and ECM cables are tight and clean. Found oil in harness leading to low oil cutoff on pan and cleaned harness, plug and sensor. Found source of oil leak to be o-ring on side of valve cover. ECM connectors are dry and clean. Drove truck again and Same issues afterward. No codes on dash.

Disconnect the big plug at the engine  ECU and wash the oil out with brake clean see how that goes for ya! just something to try! This was a common issue at one point!
