Need Electrical Help. 04 New Body F150 5.4L

Removed all cops, plugs, intake manifold and driver side head to repair bad valve. Removed Left side cat pipes as well. Had to disconnect most of upper engine harness and had to remove cpm and battery.

Repaired all mechanical issues and reconnected all electrical connectors and now when I turn the key to start the red security light on dash is still blinking steadily and I get no crank no start situation and it blows #34 PCM fuse which is injector/fuel fuse as soon as hit start.

Here are some things I have done trying to trouble shoot.

Battery shows 13.65 V

Unplugged FPDM back on rear frame rail and disconnected far left harness (looking from front) from PCM (should be engine harness), both the smaller plug that plugs into another harness and the main plug to the PCM.

Now when I turn on the key the security light goes out, the dash display says engine fail safe mode and the motor will turn over when I turn the key. This is still with the #34 fuse blown.

If I plug the engine harness back into the PCM, same no click no start.

If I leave engine harness unplugged from PCM and plug FPDM back in and turn key now it goes back to no crank no start and the security light blinks rapidly.

Only way I can get anything to turn over is far left harness disconnected, both plugs and the fdpm disconnected. Display says Engine Fail Safe Mode, and the security light goes out when I turn the key to start.

I'm at a standstill as to what to do. The truck started fine prior to me taking it down for service.

 

Found issue...and truck now starts ok. Thanks!
