ok so i dropped a new motor in my zj thursday, i couldnt get it to start i figured it out it was the crank sensor, i changed it. yesterday i put it in and it started ran great. i shut it off and buttoned everything back up to par then it wouldnt start i put it in time and then locked everything back down moved it and left it run for an hour at idle because its completly brand new i.e. pistons .30 over, high torque cam, etc. but after it ran for an hour or so it wouldnt start and im puzzled let me know thanks. p.s. when i got it started it ran great no ticks, knocks, slips, leaks nothing.
