It will start then die if i hold the gas peddal down it will run for a min but it sputters really bad and backfires it has a new crankshaft sen dont know were to go next all this just started one day


sounds like your ignititon control module is going bad,this controls you spark and timing by a electronic brain.. THe location of your ignition control module is underneath the spark coil packs. if you follow your spark plug wires from your spark plug backward to the coil packs. if it is a 6 cylinder you will see 3 black coil packs with 2 wires attached to each coil. the coils are held in place by a few screw each,just make sure you mark each coil with tape so you do not get them mixed up when you take them off, I dont know what year your vehicle is but if it is more them 10-12 yrs old and has never been replaced,then i would replace it .I know because i have experienced these same kinds of problems with my general motor vehicles i have owned..

2001 buick lasabre, no power to one of the ignition coil packs


You have 3 individaul coils each one sits on the ICM(ignition control module). Now if there is no power to one of the ignition coil pack youll have to replace the ignition module, It will be in your interest to replace that coil that has no power to it.
