02 Envoy Starting Problem

More and more regularly, our 02 Envoy will not turn over when the ignition switch is turned. Battery is fine/new. Vehicle shows no signs of life except the dash lights are on; when key is turned, nothing. Have replaced the ignition switch module, no difference. Any suggestions?

Welcome to AF, if it will not crank, check the battery connections thoroughly check for 12v at the starter solenoid when attempting to start, ( 2 man job)
