1995 Chevy Silverado starter clicks

Hi, when the problem occurs, did you try cranking in neutral? There is no relay. I'd have to make sure the battery has a full charge and the connections are good. With key in the crank position, the purple wire at starter solenoid S terminal, should be hot, If it isn't backtrack the circuit. Possibilities, ignition switch-- neutral switch-- wiring circuits.

thanks the battery has a good charge even tried jumping it off and it wouldn't crank connections are good checked them all and the purple wire is hot. i'm just stumped on what it could be thought ab replacing the ignition

Maybe a starter issue? Some of the national brand autostores will check the starter for you, if you take it off and take it to them. If you have good voltage at starter S terminal and starter bat terminal, and no starter action, I suspect the starter. You have to be sure about voltage and ground circuit. You may have to check actual voltage reading.
