Good day today as the car has been off the road for alomost a month. The starting became intermittent and finally failed just before Xmas. As I had replaced my fuel pump recently that was the first suspect but it seemed to be fine. Took out one of the plugs and quickly proved there was no spark. Checked all the HT leads and they seemed fine. Then swapped the coil over with a spare one and she leapt into life.
So went put for a lunch meet today, 45 mins each way and she ran faultlessly.
