Last night my low fuel pressure light came on and it started running like crap, bearly made it to my shop. So today I couldn't here the holley blue or my stock lift pump running, Iran a hot wire to the holley blue and primed it up then started the truck and it ran fine till it ran out of prime I suppose....where does the stock priming pump get its signal from. My holley blue pump is hooked to a relay but gets its signal from the stock pump wire...so I am guessing its not getting a signal to turn on..
