i had the whole msd kit set up in my 2000 si, and i went to go take it off to change it back to stock, and doing that messed up the rotor and the pick up magnet, so i got a new distributor and just put it in and now it still wont start. How do check my timing and if it is how do i correct it, If its not the timing then what can it be? helppp, i miss my ek9/em1
