no fuel no start

Ok so i just fininshed a full rebuild every thing pluged in and ENG is in the car put in some fresh gas and see if it fires up crank crank crank and nothing. geting code 22 and 51 posibley need to adjust TPS...

but its not even trying to start so open the fuel sender access panel in the trunk key ON no sound...then i did the bypass trick at the diag port NOTHING no sound from the pump. all fuses are good.

correct me if im wrong: next step check for voltage at the pump.

yup.
With the key in the 'on' position, and terminals Fp and +B shorted, you should hear the pump.

could i just apply 12v to the fuel connector to see if the pump goes on or not

Lubricate the injector o-rings when installing. I think Toyota recommends using gas as the lube.
