95LT188ChevyTruck

So last night I finally dropped the 383 back into my truck and about a month before I had installed my walbro 255lph pump in my truck. I wired everything up and turned the key to see if the pump was coming on and it wasn't. I am at a loss becuase I am pretty positive I wired it up correctly is there anything special needed to turn this pump on over my stock wiring to the pump? I had a stock corvette pump wired in there before and it worked fine.

Any help would be appreciated.

Thanks,
Freddie
