i had starting trouble on my 2000 5.3 and checked fullsizechevy.coms forum and everyone said fuel pressure regulator, if you pull the vaccum hose off of it and gas drips out the regulater is bad and needs to be replaced, i did it to mine and sure enough gas came out so 45 dollers later for the part at auto zone now truck starts like new hopefully that helps
