I am new to the forums and have searched this topic, but I could not nail down a specific problem.

I just put a new Delco fuel pump in a 1990 C1500 5.7 L. The problem is I am getting no power to the pump. The purple wire in the fuel pump harness has power, but nothing to the grey wire. I checked at the fuel pump relay and fuse on the firewall, and it appears that I am not getting power to these either. If I pour gas in the throttle body the engine will fire right up.

What would be the next thing to check.



Thanks for helping.
