Leroys lift pump harness

Installed Leroy's Diesel lift pump harness on my 92 6.5. It has the wait to start wire. Now the lift pump doesn't run when the engine is running, only when the glow plugs are energized. put in a new OPS ,didn't help. Haven't heard back from Leroy yet, but it's the weekend. Any ideas?

1992 6.5L 2500 4x4 Silverado Reg. cab flatbed. Things I've done: Injectors,glow plugs,GP harness, glow plug controller, lift pump, Leroy's lift pump harness, OPS.
