hey guys heres my situation my fuel pump works, relay works, fuel inertia switch is fine. im getting power to three wires in the relay. the forth wire (fuel pump wire, black and pink) doesnt get power. ive tried two different computers that i know work..different relays etc. does anyone have any idea what it could be? if i cant figure it out would it be safe to just wire in a relay of my own to a switched 12 volt? ...any advice would be appriciated

you mean the "trigger wire" does not get any power?
You can wire your own, if that's the case. You just need a source that stays on while cranking

is it a race car or street car? if it is a race car you can install a switch and turn on the pump manually, independent from the ignition switch

you can do that regardless, i know plenty of st cars with pumps runnin off of a switch, get a good switch and relay and you should be fine

Glad you figured it out! and thanks for getting back to us with the solution. Many times people post car problems, figure them out, and never post the solutions for others to see/ learn.
