That was probably a solenoid on the fender.

They still have starter relays, usually located in the underhood junction block (fuse box). On the GM's I worked on, you could often swap the starter and AC relay to see if that was the bad part.

Yep k snow, I'm familiar lol. I just thought that in the 70's charles was probably thinking of the solenoid. You could jump'em with a screwdriver.

Yep, the old steal me please option.

Tap the starter with a hammer while cranking. If you can do this by yourself please make a video…it will be amazing.

Yup, son had the same random problem a few months ago. Did it a couple of times. He had the battery checked, they told him all good, voltage was good. Did it a few more times over a month or so while he replaced alternator, looked for shorts, etc. Always started and run until the random next time. Finally, have a buddy run an old fashioned battery stress test ... Result, one dead cell in the battery. Replaced the oem battery, hasn't had a problem since.

Nuetral selection switch going bad. Truck won't start because it doesn't know its in park. Wiggle gear shift while trying to start it see if that helps

I can do that while chewing gum.

had a similar issue with my wife's expedition

it would loose enough current and the starter would click then the relay under the dash started clicking until the batter cable was pulled , could pull the ground , put it back on and start most of the time
it was a bad battery that showed it's self a few months later

cheap battery stress test , turn on headlights set timer 10-15 minutes ,then turn key if she won't start battery is bad.

. That's for sure! Too many fishing trips to Wyoming!

Tap the starter it might shake loose the brushes if the are binding up.

My 07 had that problem.......turn out to be a bad fuse box........

My starter went out a few weeks ago, it would turn over like a low battery but the battery was fine.

Mine does the same thing. Put it in neutral and it starts.

my van used to be like that , worn out neutral/Park safety switch in park , but neutral was fine

Had the same problem with Chev Equinox. Finally, after a lot of frustration I took it to the dealer. They had it for over a week and it started perfectly for them every time. They ordered me to come and get it. When I did, guess what, it WUDDN't start. Now my wife and I are doing a happy dance in the service area. IT WAS THE FOB. Guess what the cost of replacing everything they were planning would have cost. Its a thought

Neutral safety switch will do that.

It's the starter. Replace it before it leaves you sitting somewhere you don't want to be. If you made it over 100k without replacement, you are a lucky man.

The key switch???
