I'm getting 3 cylinders to fire! Just blew up my whole distributor! New cap, rotor, distributor, coil and wires! Getting spark all the way thru the wires on all cylinders! Using NGK Iridium plugs, MSD wires. Gonna check injectors tomorrow! Any other suggestions? Compression on the none firing cylinder is 130. Sort of stumped! As far as we've checked we're getting good fuel into all cylinders! motor is a B20B.
