No pump, no codes

No pump, no codes
Rebuilt truck in last 2 months. Cab, box, etc. Anyway, got everything back on and it started. Must have been left over fuel in the rails because now that I<ve put a new tank on, it wont start. Just rolls over, no pump.
Pump runs when bypassing Fp and B+ or with AMF flap open.
COR
-resistances are good
-has power on 2 coming from Main Relay
-has power on 4 going to AMF
-has ground on 3 and 6
-plug is good, checked by jumping it
AMF
-Resistances are good
-Only has power on 2 coming from COR
Dont seem to have power on VC, VS, and THA wires at ECU plug. Does power come from AMF to ECU, or vice-versa?
Had codes 24 and 31 earlier today, but was probably from the testing. Cleared them and now, no codes whatsoever. Still no pump.
