I did have a look at the fuse box, I will inspect it more carefully, thank you. Pete.

Remember there are more than 1 fuse boxes

I have checked all of the fuses, they are all good with the exception of fuse No 5 in the load space fusebox (rear electric windows) which was blown. I fitted a new one and it blew again. The car hasn't got rear electric windows! I renewed the key fob battery, still no joy. My Daughter says that previously on occasions the car hasn't started, she would reinsert the key and go through the starting procedure again, and it would go. She also reported that the engine and the service lights had come on briefly during the last trip.

Check / replace crank sensor ( if fitted to that engine ) if faulty , no spark

Here is an example ,

I fitted new crankshaft position sensor, problem solved! Thank you for your invaluable help much appreciated.
I tested the old sensor, with my ohm meter, and it was open circuit, the replacement was 2.2m ohm.

Glad you got it fixed , thanks for updating the forum .
