No start Obs 7.3

Recently put my motor back in after resealing a few things and also put on a regulated return Efuel system. Truck will crank fine but won't even try and fire. I put a new CPS in aswell thinking that may be an issue , but nothing. The glow plug solinoid is getting hot when cranking aswell , thinking maybe a ground issue and also causing the no start ? Looking for some more advice what it could be.

What exactly did you reseal? Did you do anything to the high pressure oil system? Perhaps an electrical connection is undone.

Are you building fuel pressure? Oil pump res full? Also assuming that all connections were checked? How long have you been trying to start it.

Check IPR connector.

I bet your oil pump has lost prime. Do you have oil pressure? Is the dummy gauge in the dash showing pressure?
