Went to start my truck and it turned over one time and then just sputtered as if way out of time. Starter turns the engine, but the engine never starts, but just sputters a few times and never fires off. Trying to figure out where to start looking first. Also, does the 5.3L have a timing belt, gear, chain, etc.?
