IN NEED OF HELP So I have a 1999 f250 with a 7.3 it is a 6 speed with a brand new transmission. When I first got it the owner said it had a starting problem said it was the icp sensor. what was happening is truck would start and run fine, after shutoff have to wait 30 minutes to an hour before it will restart no matter how long I crank it will not fire. Icp sensor was replaced sense then and no difference. Have no idea what it could be. It has a hydra tuner on it too and 100hp injectors. That's the only upgrades to the engine and straight piped 4" exhaust.
