Anybody familiar with JY Jeeps?
 

Mine is broke...

I'm thinking ignition issues. If we have anybody on here that knows anything about the 4.2L engine, I'll go into details.

Wow...just noticed it should be familiar not failure...spell check fail!

Fixed.

Well,

she's back on the road!

Turned out to be several things.

1. a bad coil
2. a bad ignition box
3. a failing alternator
4. several broken and shorted wires
5. ECM was only partially disconnected/bypassed...(electronic carburetor removed, timing controls still were intact)
6. lots of shitty half-assed wiring

woo-hoo!

glad its back on the road I really like Jeeps :)
