hello. i will try to give you overview,..need some help. my 96 suburban with stock vortec 5.7 crab injection. truck ran fine,..then started to skip and run rough especially after startup warm or cold. then smooth out after 1 mile. hard code of p01345 crank/cam correlation. also was running 28degrees timing and had misfire codes, mass air meter out of range, o2 sensor and lean codes. so rplaced mass air. no change, replaced distributor. double checked installation and made sure no slack in timing chain-no change. replaced crank sensor,..no change, replaced fuel punmp,..no change. then one day it sputtered and stumbled up the driveway and shut off. never ran again. checked injector pulse and nothing(not grounding),..got new computer and sent out to reprogram,..stil no run and no injector pulse. HELP!!!!!!!
