Truck died today, what happened?
I was coming back from Stage III Jammers and Fass install and the strangest thing happened. First 40 miles of the trip FP read around 20, then all of the sudden it would drop down to 3,2,1 then dead pedal. It would eventually come back while driving on the interstate after dropping to about 50 mph from about 75. This happened three times untill it happened the last time and drifted to a dead stop. Code P1694 was thrown. I was thinking VP of course but what gives with the dropping FP right after a FASS 150 install? Right now the FP reads 2 lb. and of course she won't start. Weird thing was for two of the four times the FP dropped while decelerating and off the pedal, giving it throttle seemed to help raise it a bit for a while? Also surprised I only got 25 lbs. boost with sticks & Juice on 5?

I had the same thing. loosen the filters and just bump the key so the pump runs. It may take a few times but the fuel will come out and then you will hear it prime. As soon as it does tighten the filters. it might not be the problem but it was for me. Hope it helps

Well, I just have the HPFP so would I do the same thing but with the factory located filter? Man, I'm a real newbie when it comes to this FASS stuff...

You should just be able to do it on the fass. Or loosen the feed line banjo at at Vp and do the same. That worked for me a few times. That is if your only problem is that there is air in the system.
