Tried starting this morning and it just clicks. One click, tried jumping and no go, checked fuses and all are good. Getting correct volts from battery and checked voltage at starter and it’s good. I could feel it click really hard when I had meter on starter and had someone try and start it.

Ideas???

 

Welcome to the forum. What does the battery voltage do when you try to start it?

 

Thank you sir! it drops a little from 12.x to mid to high 11 volts. then it goes right back

 

Second test is does it crank with a jump. If not I would suspect a bad starter.

 

Well this is strange to me. Yesterday I tried jump starting it from my pickup and it would not jump. I left it connected charging 10+ minutes. This morning the tow truck driver connects his portable jump starter and after a minute it started right up. He said it was me using a smaller v6 to jump it. I just had the battery tested and it tested ok. Drove it around town got back home and it starts with no issues. When I tried jumping it I had everything turned off (a/c. radio, etc)

 

Next time it just clicks, give it the "Fonzie Test": tap the starter gently with a hammer, say "Aaaaay !!!", and then try to start; if it starts up, likely a bad starter.

Likely a 2019 would still have nice, clean terminals on the battery cables, starter wires....

 

I just had to change the starter in my truck a few weeks ago. But my issue was salt corroded the copper braided wire from the solenoid into the starter motor.

 

We don't have that issue here in Arizona. Our recently-acquired 2014 Yukon lived its previous life in the Nevada desert (garaged, of course) and its engine and underside/frame/body look exactly like the showroom still.

 

A 2x4 works pretty well too. lol. Cheers. Wavelength.

 

It ended up doing it again.. I got it to the shop and it was the starter. What got me was it was able to be jumped once by a portable jumper box, but never by a vehicle.
