IT'S ALIVE.... IT'S ALIVE!!!!!! Muahahaha!!! Replaced coil pack. Did not bother testing as I already had the new one in my hand. Sure enough a .75" crack in plastic side. Replaced. Started. RUNS AS STRONG AS EVER!!!!!!


I highly recommend replacing your coil pack. The smallest crack makes all sorts of problems.
