GMC SIERRA ENGINE PROBLEM

1988 GMC Sierra

My 1988 gmc 1 ton truck only starts when it feels like it? Yet it will tart if it is pulled? Its been in the shop and the ignition & wire were changed! All the other motor stuff has been changed? Im a mechanic and I just cant figure it out!

SORTA EXPLAIN IN FULL, EXACTLY WHAT HAPPENS WHEN YOU TURN THE KEY TO "START". UNTIL YOU RELEASE IT

"START" IS SOMETIMES THOUGHT OF IN 2 WAYS

1) THE "TURNING OVER" ASPECT (CRANKING)

2) THE "BUSTING OFF" AND "RUNNING" ASPECT (RUN)

SPECIFICS ABOUT YOUR TRUCK'S NOMENCLATURE AND FEATURES. AND ENGINE SIZE INFO, REALLY HELPS US INVESTIGATE YOUR SOLUTION WAITING TO HAPPEN!
