double check ground from battery to motor

do you have a computer chip in the key if you do, most common problem is the wire on the ignition switch is broken , to fix it you need to change the the key cylinder which involves removing the steering wheel , if you've never done this before find someone that knows how .

Check that the crank angle sensor is working, it should give an on-off (frequency) signal. Or check the resistance value across the two terminals.

i am willing to bet the vats system does match the ecu

im the owner the, the vats system was by passed no broken wires, the fuel pump dose not kick on at all no spark, no injector pulse, the check engine light dosent come on when u turn key to on pos is the a diffrence between the fuse boxes in a v6 car v8 car?

i believe the wiring is different on the 2 cars. check for power going to the ecu. which method did you use to bypass the vats. some are better than others. you can also go into the ecu tune out the vats system that way.
