    F250 NO SPARK CYL 5 AND 6

    MY 2006 F250 MODEL NUMBER F250TUR has no spark on the bottom port and bottom starboard cylinders. I swapped coils and even installed a new coil but it's NOT the coils.

    What tells coils 5 and 6 to fire? Pulser coil, crank position sensor...?

    Can a bad pulser coil shut off only two cylinders?
