Why is my next question.
What was wrong with the OEM Harmonic Balancer?
Are you throwing any DTCs?

if you changed it because it came apart ( pretty common with the 4.0), alot of times it will trash the crank sensor or maybe the wiring thats mounted right behind it. i replaced my oem pulley once then went with a udp the last time. but i havent had your issue
