I started the truck up thanksgiving morning let it run for 20 mins, left my house and went 1/2 a block throrrle stuck wide open so i shut the truck off and went to start it again --- no start and smoke was coming from the relocated pmd ( which was replaced 4 years ago),Lift pump is working, have fuel to IP or atleast to the bleed valve crack injector line no fuel there.. tested fuel shutoff solenoid tested good Im lost now. btw replaced pmd and still no luck.... Is it possable that the ECM crapped out ?
