2004 Chevy Silverado error codes P0200, P0300, P0446 truck

Engine Mechanical problem
2004 Chevy Silverado V8 Four Wheel Drive Automatic 85000 miles

1st i was backing out of the drive way, when i started to go forward the engine died. ( it was a cold morning) the engine would crank but would not start. I put a code reader on it and it would not read any errors because the engine would not start. I replaced the fuel pump and it started, i shut off the enigne to bolt down the tail bed. After the tailbed i started it again. It started but shuttered and died. i replaced the fuel pump again. Would not start. i tried resetting the ECU, charged the battery, and kicked the truck a few times. I went on vacation for the week, when i got home the truck started right up. I let it run for a while. the next morning i started and let it run. i turned of the truck then bolted down the tailbed. I went and borrowed the OBD 2 tester because the check engine light was on. i had the error codes P0200, P0300, P0446. I reset the codes then restarted, the errors came back. i cleared the codes again. I put it in drive and made it about 50' then it started shuttering and shutoff again. i then when and got the noid light kit to find the one wire not working.
What can i do to fix my truck??

check for an open or short to ground on that circuit.also check inj 1 fuse and inj 2 fuse,becauseThe INJ fuse also supplies voltage to the ignition coil modules. If the fuse is open, inspect all related circuits and components for a short to ground. post back with what you find.
