03 Buick Century no power at Fuel pump relay
03 Buick Century has no power at Fuel pump relay.
The relay coil has power and comes on.
There does not seem to be any power supply for the pump to run at the relay.
I can supply fuel pump with voltage from the battery and fuel pump comes on.

you'll have to check to see if there is a bad connection at the computer or relay not letting it go on. It's a dark green wire with a white stripe. also check the ground wire, it connects to the trans stud

I'm saying that the relay coil is powered and comes on without a problem.
Problem is with the main feed coming into the relay.
Can you post a diagram? thanks

here is the diagram. hope you have checked the fuse underhood, it's #35 if the pcm doesn't send a signal to the relay though it won't come on either.
