ok this will be long so hang with me i no i had a fuel press issue so i put the fass system on so thats no longer an issue but about 6k miles later if i drive the truck for 200+miles or 3 1/2 hours straight it will start acting up especaily between 1300rpms and 2000 like its getting fuel and then not finaly thursday i drove it long enuff it had a dead pedal for bout 5 seconds but if i stop for 15 to 30 min (either leave the truck idoling or shut it down) then runs like a champ again for another 200miles??? another thing since i put the fass on sometimes not all it is hard to start meaning i have to let it turn over for 3 or 4 sec before it fires but once it fires it runs smooth not ruff like it got air so am i looken at vp time here o an im not getting any codes with this
