Or any number of other issues.
So go to Utube and look up "Voltage Drop Testing" a Starting system"
Once you understand how to do the tests it will be much simpler to find electrical issues like your having.
All you need to do the testing is a Digital Multi Meter.
The hardest part of the testing is having access to the electrical connections and components.

I got back into the engine bay yesterday (finished up other projects). Ashamed to admit the positive cable nut at the front junction was loose. I had to drop the engine like 3 times as i was reassembling to fit things that could not be done (PS reservoir, parking brake cable, etc.). Fingers crossed that was the issue!

First rule of diagnostics:
Always check what human hands have touched first.

No kidding. I'm still going to swap in a bosch starter to replace the chinese one - will make me feel better.

On a positive note, my cruise works with a new brake switch, and I passed the catalytic converter OBDII monitor! It had failed, so instead of babying it, I gave it a few pulls and drove her hard. Ole eye tall ee an toon up.

Just waiting on evap & secondary air injection and I'll get it fully plated.
