Wiring for fuel pump
 

No Power to Wiring at fuel pump. Traced it all the way back to the fire wall and nothing. What relay or fuse does it get power from .... 94' K5... :scare2:

you can check the LP under the dash by running a jumper wire to the G terminal on the ALDL port under the dash open the T valve under the hood then apply power to the G terminal if the LP works its probally the OPS

Splice a wire from a key on fuse wire (cruise control, gauges, or the ign on radio)
to the grey wire on OPS and you will have your lift pump running whenever truck is on.

We know the fuel pump works. Trying to find a Wiring Diagram so that we can chase wires...:s:

Relay is on the firewall

here you gp
