Always start with the basics. Try to verify the FASS has power when this happens (listen for it running, or verify with VOM). If it has power and it is running then move on to either verifying fuel pressure with a second gauge, or check all wiring for you fuel pressure sender. If you don't have a needle valve before your fuel pressure sender it is possible it was damaged by the IP pulses.
Fuel Pressure Problems, Please HELP
I was on my way to work and my fuel pressure went to zero. I stopped let it sit a minute and then started back up and was fine. Then after about 200 feet it went to zero again. I have a small leak coming out of the fuel filter housing where the wire goes into. Was just curious if this is causing it or if its something else. Fuel pressure gauge usually reads aroung 24 psi, now it reads around 18 then drops to 10 then drops to 0.
I have stock vp44, fass pump, adrenaline chip, k&n air filter, 5" straight exhaust.
