2002 Suburban will not start or turn over. Lights and everything have full power.

First make sure your battery terminals are clean & free of corrosion as well as the connectors. Enough power can come through to power lights and not be enough to turn the engine or click the solenoid. If that doesnt do it then I'd say you need a new starter. I always replace the solenoid (or Bendix as the old school calls it) when I replace a starter.

Have some tap on starter with hammer,while turning ignition on,,may have starter problem
