I need more information...

what engine? 5.7? How does it start up? Long crank? start up right away? Starts and stutters? starts and idles okay but won't accelerate? Revs up in park but put in gear and stumbles? Can't be driven? Can be driven but runs rough? Start from the first time you noticed it wasn't normal and what happened from there...
