Engine cranks fast but takes a while to start. After it starts I can shut it off and it will start right up. Get gas and come back out starts okay. Go into restaruant to eat, come back out , takes a while to start. New plugs,wires,coolant temp sensor,starter,and fuel filter.
Fuel pump and relay,tps sensor,mass airflow sensor,bat voltage, and alternator are all okay. 89 iroc runs great. Any idea what makes it hard to start?
