If the pump isn't priming, that's your issue. Get yourself an inline fuel pressure tester and verify it isn't getting any pressure. Check voltage at the pump to verify the new unit isn't bad.

This is what I found out the pump has no power but is good ran 12 volts to it and it ran, but even with it running the car wouldn't run, no pulse at the injectors either.

Check the CAS. Turning it manually by hand should cause the injectors to click.

mine seems to be having the same problem. I have noticed it happens more when it's cold out.
