YJ 4.0 question

[rpf500]

YJ has been shutting off randomly when I depress clutch to get ready to stop. Coil seems like a common item when I googled it. It always starts right back up. May do it once all day, or maybe 3 times. Any thoughts?

Crank sensor would be a prospect....

X2 on crank sensor

Thanks guys. I'd always thought those either worked or didn't. I'll add it to the list

Re:

You can check the crank sensor with a dmm. It will give a certain value of resistance to keep you from having to mess with that crap, just check it at the plug. Google the resistance it should have and compare.
Edit...
1.Near the rear of intake manifold, disconnect sensor pigtail harness connector from main wiring harness. 2. Place an ohmmeter across terminals B and C (See Image). Ohmmeter should be set to 1K-to-1OK scale for this test. 3. The meter reading should be open (infinite resistance). Replace sensor if a low resistance is indicated.
