Extended Cranking Time When Cold
I have a 1996 Chevrolet C1500 extended cab pickup with a 5.0 liter (305ci) V8 and an automatic transmission. Truck has only 60k miles. Lately, I've noticed that I must allow the starter to run longer to get the engine running when cold. Starts promptly when hot, and runs well otherwise. The check engine light is not on, and I have had the ECM scanned for codes and none are present. How should I proceed with troubleshooting and correcting this?
Much thanks in advance!
