The truck ran with this unplugged, but would that keep the fuel pump from priming?

The way I read it the module overrides the ECM which shuts off the prime after 2 seconds or so and it continues to prime the injectors until the truck starts.
The oil pump sender should cutoff the module priming function after a certain pressure is reached. without the oil sender, the truck may have to crank longer to build enough pressure start. Honestly I haven't had much experience with these so maybe some others can explain it better.

I would say that you could get away with replacing the oil pressure sender and either wire around the hot module or replacing it. VV
