Hi there, I am Cam. Can I get your name please? YEs the relay is a good thing to check next. Can you see if removing the relay and jumping pins 30 to 87 using the numbers stamped on the bottom of the relay make the pump run? the relay is mounted on the side of the underhood fuse block.

Does this relay run both pumps?
Expert:  Gm Tech (Cam) replied 1 year ago.
There is only one pump, but its up to the solenoids to determine which shock fills.
