[QUOTE="Trqmnstr, post: 900512, member: 12776"] Not positive but i would think if your fp is way low the truck probly wouldn't want to start good. If you wait till the pump shuts off before you crank the motor its always gonna crank a few more times than when the pump is pressured up before it fires, even with a good pump. You said yours slowly builds pressure so if your waiting for the inductive heat cycle to stop on cold days your pump is off before you crank the starter. Its pretty easy to hear when the pump shuts off, im guessing around 20 seconds after you turn the key on, obviously your fuel pressure gauge is gonna drop to zero when the pump shuts off. So the motor is probly firing when the fuel pressure gets to a certain minimum psi and its taking the pump a while to get that pressure built up. [/QUOTE]
