Angry 03 x5 4.6is rebuild problems

Hello, new poster here
I just finished a top end rebuild minus head gaskets and installed new (used) transmission. Both worked great before rebuild. Everything appears to be plugged in and tight.

No start, cranks but won't fire.
Codes: p0741, p0734, p0721, p0600
Dash cluster no longer reads at all.

Has a bunch of new parts that were installed during rebuild.

Please help. Thank you

Sounds like the above is not the case. Grounding wires?

Crank no fire prime suspect it's EWS.

Do you have bidirectional scanner that can test and reset EWS?

Dash cluster no power? Scanner like foxwell can run a self test as well as hidden menu but only if the dash can light up.
