Error MSG Reduced Power to Engine
2014 2500 Silverado 6.0 liter, had 5th wheel plate put in last Wednesday, drove it home parked it would not start Saturday morning got error msg once that said reduced Engine Power, no crank no sound no clicks nothing. Checked all fuses under hood and cab all good. (thought maybe electrical because of 5th wheel). Battery fully charged, tried jumping it even with full battery and NOTHING when turn key. Research says reduced power may be throttle or transmission when moving but can't even get it to turn over.

So here is the Diagnosis bad ECM needs replacing to the tune of 728.14 That includes tow. Further in this forum about page 3 someone else got the Reduced Engine Power mgs and it was their ECM/ECU as well. I hate computers
