Do you have power at the injectors?

It turns over fine but will not fire with new coil, new computer, new auto shut off relay, and good fuel pressure.
I have it at a garage but there having problems for a while now

Check the dark green and orange wire for power at the injector it shares the same wire to power the coil-Your turn

So the car has no power at the injectors or the coil. I've tested the auto shut down relay and its good. I've check both the cam and crank sensors and they are good as well. There is no codes stored in the computer when I try cycling the ignition.

Voltmeter/CT: Probe the red and white wire at the ASD relay harness do you have power? If not check the fuel pump/Trans fuse in the power distribution center if okay, the wire is open between the relay harness and the fuse-not open the ground control circuit of the ASD relay is either open or the computer itself

The fuel pump is new and we have good pressure

Since it has good pressure it tells me the FP works and the FP relay-Did you check for power at the ASD relay on the red and white wire-you need to do this before I can continue-
