2014 Tahoe sometimes does not crank over,?

Question

Once in a while when it doesn't want to crank over it starts to crank over with ignition in start position but just clicks then nothing and then nothing at all with every tempt to start until ignition is turned all the way off and retry then goes back to normal but will still act up once in a while, have any idea what is causing it or what I may try to get it started in case it decides to not start permenately and I end up stranded some where? I have noticed remote start did not start it a couple of times I was standing next to it and pushed remote start and it clicked and did not start, the battery is good. I hope I do not have to wait until it goes out permenately before I can figure out what is going out, maybe someone has experienced this early warning...? Thank You...

Could be as simple as a bad start relay, bad ignition switch or bad starter. These systems work by first checking to make sure you're using the right key. The receiver reads the key code off your transponder key, sends it to the body control module which then sends the digital key I.D. to the PCM. If it's the right key, PCM tells BCM it's ok and THEN it provides ground to the control coil portion of the starter relay in the fuse box. That closes contacts and sends power down to the starter solenoid. The starter solenoid pulls in another set of contacts to supply battery power to the starter. So you need to check when it won't start to see it the starter is getting voltage from the fuse box relay. If it is, then you have a bad starter/solenoid. If not, then you have to work your way backwards to see if the fuse box relay is bad or if you have a problem with the antitheft system.

You need a new starter. That one has a dead spot in armature.
