On my way home tonight car started intermittently misfiring. Got home and fiddled about under the bonnet-car would run but sounded like on 3 cylinders. Now car does not even start. I have removed spark plug still connected to HT lead and checked for spark when starting car and no spark can be seen, (this was done on 2 different plugs). I'm guessing a coil/distributor problem.
What should I be checking for next to pin point the problem.
Help appreciated guys
