Truck will not turn over, need code help please

Hi, New to the forum and hoping someone can give me some insight to the codes my truck is showing. To give a short back story, it died completely including the instrument panel while backing out of my driveway. I trouble shot the issue with a friend and replaced the accessory delay relay, fuel pump relay and PCM relay with no luck. I then went through the interior fuse box and found the ignition control fuse blown. Replaced that which gave me power back at the instrument panel and was able to run my OBD2 scanner. I also checked for corrosion and faulty wiring at the battery and starter, both are fine. I recently replaced the fuel pump, and fuel filter as well. The codes I'm getting are P0091, P0627, P0090, P0001. Does anyone have any insight as to what to check next?

Just doing a quick Google search of the codes you posted would tell me to check that new fuel pump you put in. Sounds like you have an open circuit/short somewhere. Double check all the connectors.
