First some background:
I purchased an '88 iroc with a 305tpi, 5-speed and procharger p600b with a 13psi pulley. I bought it knowing that the fuel pumps wouldn't prime and now that the car is home I'm trying to diagnose the issue.

With the key in the "on" position nothing happens. After cranking a couple times something primed out back(i was working alone so im not sure which pump was priming) and then started spraying fuel out of a leaky hose so that ended the night. Today I went out and directed the leaky hose into a fuel container in order to try and empty the tank. Now with the key "on" and cranking nothing primes.

Boon believes it to be a wiring issue so can anyone give me an idea where to start looking for problems?

Also, I was contemplating doing something like a single or double walbro 255 in-tank and eliminating the fmu and auxiliary pump. Any thoughts on that?
