Chevy 1995 silverado hard to start - 1995-1997 Chevy 1500 Truck Ignition Starter Alarm Switch

Is the engine slow cranking, hard to start or cranks over but will not run? Slow cranking would be battery or starter problem and the cranking but not running could be a fuel problem or lack of power to the ignition system. When it does not start, spray a little starting fluid into the throttle body and try it. If it starts, bad fuel pump or relay. If a no start continues, pull a plug wire and check to see if it has spark.
