changed the module, no spark. changed the coil, no spark. went back to basics, removed the distributor cap to check the rotor condition and if it was turning, when we turn the motor over their were sparks flying off the coil wire, it had gotten worn but we could not see at the time because the area was hidden but we could hear the sparks. replace the wire and all is well. a new set is on order for all 3 of my mbs. Again thank you for your assistance.
