I just discovered that my pump is not getting any juice. I've traced the wires to the fire wall, but still no power. Any suggestions? This is for a '77 280.
Thanks.

How did you figure the pump has no power? Previously you posted that your fuel pump would always run in the "ON" position, that is wrong! Either the AFM fuel pump switch is broken closed (they normally break to open) then something else is wrong with your electrical. It's very possible that someone has previously "repaired" this same problem. The things you need to check are the AFM fuel pump switch and EFI relay ... both of which have been covered in the archives. Here are some posts to help you understand the system a little more.

Thanks Conner! I really had no clue that it was NOT supposed to work that way. I WILL heed your warnings and take action on the links you sent me! I REALLY appreciate the info!
