2007 Ultra, stock engine, thunderheader exhaust, high flow air cleaner, stage 1 download to ecm. The bike starts fine when cold, but after riding and getting to operating temp, if I shut it off for a short time, as in filling up with fuel, the bike doesn't fire right off as it should. The starter turns the engine over fine, eliminating the battery & starter as the problem. I hooked up a fuel pressure gauge, and it has 60 lbs of fuel pressure when running, and holds at 52 lbs when the engine is off. Maybe the computer thinks the bike is cold, not sure. Usually starts after 2 or 3 tries, and runs fine. Any thoughts?
