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.
