Well here's the back ground I was trying to get my j10 running and troubleshooting that when the Cherokee took a dump too. I swapped my cherokee battery into the j10 to confirm that was the problem with that (which it was). But when I put the battery back in the Cherokee that thing won't start now.
Here's what it's doing:
Has power when you turn ignition over to accessory. When I turn the key to start it only engages the starter (can here it engage/spin). But won't actually crank the motor over.
Here's what I've troubleshooted:
- pulled the starter and got that tested (came back fine)
- still bought a new starter to just make sure and when I put the new one in, I still have the same issue/noise.
- got the battery tested and that came back moderate. So I haven't actually bought a new one yet. Might swap the new j10 battery in tomorrow to test that.
- pulled the crankshaft positioning sensor off and cleaned that up a bit. (Could only really wipe it off)
- checked the ring gear and the teeth aren't stripped on that.
- tried putting it in neutral and starting it. No luck.
That's where I'm at with it now. Still doing the same thing. Not sure exactly where to go now. Not sure if I should get a new CPS to see if that is it? Or the battery? Or could it be a neutral switch that won't let it engage to the ring gear? I have had some issues with that before but hasn't been acting up lately so not sure if that would cause this.

!don't hug that tree...I'm about to run it over!
Make sure the battery cables and terminals are clean and tight.
Try a known good battery.
If the starter cliicks but doesn't turn the engine over, the problem most likely is in the battery, cables or starter.
You have already had the starter checked but bench testing isn't the same as actual use.

Starter spins but does not crank engine...
(1) mechanism inside starter that throws gear out to engage ring gear is busted. Replace starter. Or...
(2) one-way clutch on starter gear is slipping. Replace starter. Or...
(3) ring gear is stripped. Replace flywheel/flexplate.
But you said the ring gear is fine, and you have replaced the starter. Hmmm... I have no idea.
And you said you removed the CPS. How did you adjust the clearance to the flexplate when you reinstalled?
The road goes on forever, the party never ends....
The CPS is plug n' play. You don't need to adjust it. Even with that, the tell tale symptom of a bad CPS is crank and crank and crank. Since you're not even cranking, that is not your problem. The starter solenoid is suspect here...as is the battery, AND the connections. Just because the lights and bells come on does not mean there's enough juice to turn the engine over. "Moderate" is not "good". Swap out the battery, see if it helps...or at least jump it, or put it on a charger overnight.
