Question
engine turns over starts maybe 1/2 second runs and stalls
battery good new pick up coil have good spark
good spray at injectors new plugs

Answer
Hi Jim...check to see if you have power and ign referance at the ign module. sounds like it is breaking down after start up. if ok, do you have fuel spray after it quits. check fuel pressure. try pinching off vacum to fuel pressure regulator that will drive up pressure if there is not enough. make sure relay running fuel pump is not shutting down after starting. do you have any codes...map sensor will cause this as well
hope this helps... merry christmas
