Good day guys, i have a 2012 silverado and im having hell of a time figuring this one out. No crank but battery is good, pulled the starter and it tested fine. Lead to starter motor has same reading as at the terminal
couldnt get a reading from the wire to the solinoid. Relays all respond, fuses tested fine. No codes populate. Anyone know what my best course of action is?

 

You need to put a meter on the solenoid and see if you get 12 volts when trying to start.

 

Mine turned out to be the connector to the starter. It was crispy from heat and had cracked. Someone was kind enough to break off the little red lock on the connector so it went on ok but it was cracked and I think opening up under high heat causing a loose connection. It started fine in the morning but after I drive it for awhile, it wouldn’t start. Might be worth a closer look. Got a new connector with pigtail for like $15 online.

 

I have a 2003 tahoe. For several months I would intermittently have instances where I'd crank the key over, with no noise or action whatsoever from the starter. However, I could generally tap the starter once and it would then start with no problem. Let me back up some and also point out that I've had something drawing my battery down for several months as well. I've been disconnecting the battery when I'd get out (With a quick disconnect switch) . So last night my luck ran out it appears and the "tapping" the starter did not work after several attempts so I had to be towed home. So I pulled my starter off today and checked it with jumper cables and a battery, the starter turned fine but the bendix did not kick in. I'm just wondering if the tapping that was working previously was freeing the bendix to kick in or if it could have been a loose connection. It seems to me if the bendix was "stuck" it would have still made a noise around the starter. Thoughts appreciated though I'll at least have a new starter tomorrow.
Thanks.
