help! fuel pump wont run!

[fireheadmt]

just tried starting my sr for the first time. the fuel pump will not run when i turn the key on or crank the motor. i am getting power at the pump and i can run the pump just by sending power to it manually. i am getting power at the relay and at the ecu. the strange thing is i am not getting a ground shot back from the wire for the fuel pump in the ecu when i crank the motor.

any ideas?

thanks in advance

found this on heavythrottle

Fuel pump not coming on Plugs by Battery may be wired incorrectly, they plug in but won't work without rewiring. Pump should run for 3 seconds then stop if flywheel not moving.

how do i know if they are wired incorrectly, and any other ideas?

How about you give us some info on what motor you have, and what car you have.
