Hi Graham,
Many thanks for the quick response.
Besides me, a car technician has made same checks as I did before.
All fuses in fuse box and ajacent OK.
Spark at the plug OK.
Tank can breathe, fuel available at the ramp.
Relays have been changed.
Are therer any "hidden" relays in other areas than the fuse box?
Does the ECU carry a fuse or two?
Could an immobilizer (Serpico car alarm) block a solenoid from working?
Wanted to be ready to go to Le Mans Classic in the Mk IV this Thursday, but am afraid I'll have to use another British car for the trip
