1997 Dodge Ram 3500 – 12-Valve Cummins (P7100) – Need Help Diagnosing This guy explains all my problems almost to the T. https://www.youtube.com/watch?v=1xUy3NF_Ma8 I've been chasing a fuel-related issue for a while now, and here's the timeline. Truck cranks no start starts with ether/starting fuel Took it to a shop they diagnosed as an overflow valve. Changed that and same exact system Fass system installed. It works because i tried bleeding and it getting to the injectors. Shut off Solenoid is functional Idle Screw has been adjusted At this point i'm not sure what this issue is. I plan on taking it to a different shop that specializes in diesel. I don't want to wrench it on anymore... I'm exhausted all my options Any diesel mechanics or recommendations in the seattle area?

1997 Dodge Ram 3500 – 12-Valve Cummins (P7100) – Need Help Diagnosing I've been chasing a fuel-related issue for a while now, and here's the timeline. Original Symptoms - Truck would randomly stall when put into reverse. - Replacing the fuel filter would temporarily fix the problem. What I Tried - Replaced the mechanical lift pump. - The truck improved but would still stall occasionally. - Increased the idle speed with the idle screw, and that seemed to solve the problem for a while. Problem Returned Eventually, the same symptoms came back. I repeated the previous repairs, but this time nothing fixed it. FASS Conversion Thinking the factory fuel system was the culprit, I: - Deleted the factory fuel filter housing. - Removed the mechanical lift pump. - Installed a block-off plate. - Installed a FASS fuel system. Current Symptoms - The FASS primes with the key and supplies fuel to the P7100. - The truck will not start on diesel alone. - It starts immediately with a small amount of starting fluid. - Once started, it will sometimes idle on its own, but other times it needs throttle to stay running. - Without starting fluid, it only cranks—there's no attempt to fire. After spending a lot of time troubleshooting, I finally decided to take it to a diesel shop for a proper diagnosis. Based on this timeline, what would your diagnosis be? I'll update this post with the shop's findings once they call me.

Anyone install a fass system before?
