1993 Mazda MX3 with a 1995 2.5 Millenia engine. Strangest thing - it will not start with 6 spark plug wires plugged. Unplug one - any one - and it will start and run fine on five cylinders (the unplugged one has to be grounded to a spare spark plug outside). New spark plugs, rotor, cup and tested wires. Coil? Distributor? Computer? Help!!
