Detroit DDEC-V stalling and misfiring

[Brock]

I removed the check valve from the back of the head and opened it to inspect it and everything's fine, and checked the check valve on the Davco, fuel drained from head. Filled davco back up and have been trying to crank the engine for a while now with no luck, it wont even start with ether.

Level in Davco isnt going down so I'm going to break the fuel line and see if the pump is even pumping fuel.
