You will see several threads from me on my fuel system and I have spent a lot of time and $$ trying to get it just right. I recently gave up on the full pressurized system and drilled a hole in my gas cap to keep the pressure from putting fuel into my carbon canister. It has been working great as long as I don't fill it until today.
We were doing a climb to Kingston peak, about 12K when my engine sputtered and acted like it was missing and died.
I got strapped to the bottom of the last steep hill and was able to get it started and running if I kept it at 3000 RPM or higher. Once it dropped down it died. I started it a few times and it died before I could get it in gear and get the RPMs up. Fortunately the way down from the peak was all downhill and I was able to coast to the highway were I got it towed home
I want to see if I can determine if its a Fuel flow problem, the EFI Computer or other issue before I figure next steps
I don't understand a lot about fuel systems so any advise to help isolate the issue would be much appreciated
I have a 383 Stroker with a Holley 550-810 Multi-Port Fuel Injection that both have been working great for over 5 years
My old Gas tank was leaking so installed the Man a Fre pressurized 22 Gal tank in the rear under the bed. Its my only tank
They added a Carbon Canister and pressurized gas cap. Fuel would go through the carbon canister making the truck stall, Didn't seem to be that today
They then added the 40 stock vapor separator and a one way valve to keep fuel from getting into the canister
I was still having issues only when I filled it, so now only fill it to the 3/4 level and that at least seemed to take care of the running issues
I also was still getting a fuel smell in the engine bay, so I drilled a hole in the Gas Cap and gave up on the Pressurized system
When I had the issue today, I took the cap off and no pressure issues. I even removed the grommet around the cap to provide a greater vent
Even now sitting in my garage at home it won't start, so not an altitude issue. At least anymore, potentially altitude could have done something to gum it up
I changed the fuel filter about 300 miles ago. I know that is a potential
Looking for some advise on how to isolate the problem. For example, whats the best way to see if their is fuel flow? I don't know if I should attack the computer, the fuel delivery or other.
Thinking if I disconnect the battery the system may clear. Is it possible the learning program did something?
