hi mate, ive checked the spark and there is no spark, i obtained a new coil today and fitted it and still no spark, i have tested the four wires to the coil and two stay permanently earthed, one becomes live with the ignition switched on and the other does not do anything, just permanently neutral.
Many regards ste

Think the first thing to check (besides B+) would be the distributor module, and the pick up coil second.
