first start engine turns over alot
hard starting on 2000 Chevrolet Silverado 1500
Your truck may be loosing its fuel prime. Connect a fuel pressure gauge. After truning off the engine the fuel system should hold pressure. If it does not chances are the fuel is draining back into the fuel tank due to a faulty pump assembly. If the fuel bleeds of slowly that may be ok as long the pressure comes back a soon a you turn to key on to start the engine.
