Starts by hitting starter?

Connolly73

I have a 2002 Chevy 2500hd 6.0 gas engine. Just replaced the battery and alternator less than a week ago, after 2 days of them being replaced and the truck running great again the truck 1 night didn’t start. When I turned the key, the lights and radio and what not came on but when I crank to start it nothing happens. No cranks no grunts nothing, the lights shut off and that’s it. Now I tapped the starter while cranking the key last night and it started, today it started without tapping the starter or jumping it. Is this a bad soleniod or starter or something electrical? All my connections for the battery and alternator are clean and tight. Thanks

This is exactly how my old vehicles behave when their starter solenoids begin to "stick." Replacing the starter clears it right up. However, on a 2002? I'm not sure how "old school" that particular piece of machinery is on an '02 2500, but if tapping worked, then it's probably the same deal.
