89 cherokee with 4.0 L went 1\2 mile and died, dragged it home wouldn't start. Two days later started went 2miles down road and died. Dragged home, won't start, tested ign with timing light and no spark at coil. Replaced crank position sensor and still wont start. What next?

 

there's a big relay by the battery .. if you're standing on the passenger side take of that goofy plastic sheild and it's on the right .. i'd be looking there first
