cfd511 Posted 2 hours ago Share Posted 2 hours ago Any of you fine fella s have issues with a 2015 mack granite mp8 engine just shutting off randomly. changed the engine harness, replaced all the cups, fuel pump, and found a bad ground. truck now starts quickly but really has no power under a load. pulling a volvo 160 and has a hard time getting to 30 mph. Put new fuel filter housings and boost pressure sensor. Have mechaic check valves again in the morning.
