My jeep died while pulling in out of the garage. Just fired up rolled 3 ft and was done. Would crank but no start. Following day checked fuel and spark. Good pressure on fuel. Spark was iffy. Changed cps, no change. Checked spark at #3 seemed good. Still wont fire up, doesnt even pop. Changed spark plugs this morning, nada.. changed coil tonight after checking it, was reading .3ish ohms not .5. Still no change. I need help. Friend suggested the stator.

We did a compression check and it was low, Ken suggested putting oil in the cylinders because with all the cranking i may have washed them. So thats what we did, twice. 1st time it sputtered & fired briefly 2nd time a gave it some gas and it fired right up the cranking i may have washed them.

If you're on the West Coast, the fuel might also be an issue.
I'm not sure of Cali-regulations, but Ethanol levels might become something tonwatch out for, if you're riding it hard.
