Need help! Did injector replacement on 04 6.0 to include blue spring, stand pipes. Truck ran for 40-45 min with no problems. Shut off and started several time no problems. Shut off for the night next morning no start. Did ipr and had buddy with Marco scan tool everything looked good. Ficm 48v, pressure is good. I went ahead a swapped out cam sensor. I looked a every connection several times can’t figure out ran like a champ until I shut off for the night. Any ideas??
