"I love it when a plan comes together!" No one of us is as smart as all of us working together can be! Congratulations on solving the problem. Over 60+ years of doing, and teaching auto mechanics, I've found that electrical diagnosis is one of the most difficult things to teach. Most people have a very hard time visualizing current flow, since they can't see what those electrons are doing!

Thank you so much, you guys are amazing. Frustration over!
When I just had my pinched wire issue recently, it resulted in a plume of white smoke. That really blew my legs out until I found the cause (with help from this site), so I know how you probably were feeling! Glad your issue is fixed!

I had a similar issue with another car I had years ago. The prior owners rigged the starter wire harness with a giant wire nut. One day I went to start the car and it was stone cold dead. Battery was fine, alternator fine, starter fine, I fought with it for 6 mos. with no luck. One day I was cleaning stuff in the garage, and from a different angle, noticed a small, thin wire hanging down near the firewall behind the engine...

Well, what a difference a day makes. Went out to start the truck and had the same problem - turns over once or twice then stops. Rechecked all the connections which seem secure. Frustration returns.

So to be SPECIFIC, which we really really need here, "then stops" means with foot pushing on pedal, starter turns motor over a few revolutions, then still pressing on pedal, starter no longer operates? All is dead? no sound and no starter trying to rotate motor?

Do you have a multimeter? If so, set to DC volts and place probes on pos and neg posts of battery and report reading. (not on the cable clamps). Next see if starter spins by hand operating the button on top of starter.

I get 6.29 volts at the battery. When I depress the foot pedal the engine turns over once or twice, then a pause, then once maybe twice, and this pattern continues. After my last attempt to start when I looked under the hood there was a small amount of white smoke near the starter. Not sure if that is because I held the pedal down longer than I normally do or if that is an indication of a bigger problem with the starter. The fact that it worked yesterday but not today, makes me think it is still a ground issue, but I am at a loss. The starter does turn if you push the button. Appreciate any help.

When turning over once or twice, is it fast'ish or slow? Barely rotating? or fast then stop? If battery is not breaking down during load, which you can't tell unless a load test is done, then it does sound like a starter problem. You can use a 12V battery to see what happens. It won't hurt the starter if you don't lay on the pedal too long. That may identify a bad battery or a bad starter. I don't think you have a ground problem if you cleaned where the cable attaches to food pedal bracket or to starter bolt. Where is it connected now? For turning over motor, there is only one ground that matters, the negative cable attachment. I assume you have checked the positive cable clamp and battery post and the negative clamp and battery post and have shinned up everything and tightened.

WARNING Advise us BEFORE you do the 12V battery.

It might be a timing issue. I noticed the same behavior with my '28 four banger. The fix (for my problem) was to make sure that when trying to start the engine, the spark happens at TDC, not before.

If the spark happens before TDC, the explosion is pushing AGAINST the starter and the starter has to push through the explosion. If the spark happens AT TDC, this 'push back' is not there and the engine turns over nicely.

Hope this helps. Dean

I went through everything again and kept on coming back to that it had to be the starter. I took the starter to a different shop and they found that there was a short happening internally of the starter. They made some repairs and I just put it back in today and the truck started right up. Thanks for all of your help.
