1997 k1500 no start

If it cranks long enough, have a helper crank it, while you visually check for spark at the plugs. Spark everywhere, use a gage and check fuel pressure.

If you think the starter itself has a problem, take it off, some of the national brand autostores will test it for you. Sometimes I Take a starter off and lay it on the ground, hook-up jumper cables to starter from battery, just to see if it will kick out the pinion gear and spin. That is a no load test, so, may not be conclusive?
