I am having a problem with my 2002 Chevy Tahoe. All the dash lights come on when I turn the key but starter does not crank. The battery, starter, alternator, and underhood starter relay are all new. It happens every so often, not all the time. Sometimes I have to hit the keyless remote a few times to get it to crank or just wait until a hear a click under the dash (after a few minutes). Anyone know which relay I need to replace and where? Any other possibilities or suggestions?
