I have a 2005 Ford F150 5.4 had the timing redone in it new cam phasers new tensioners new VCT solenoids and new timing chains friends / mechanic done it for me after putting it back together truck will not run have replaced new starter new fuel pump assembly friend and I tried a new trick and sprayed Fuel into the breather box and we then would turn it over and truck would run but would not stay running unless we kept spraying fuel have replaced multiple fuses in fuse box and now truck still will not fire and run completely out of ideas an fuse box gets really hot an has a burnt smell to it???
