Q: It takes 10 minutes with ignition switch 'on', after which time cranking the engine generates a spark.

asked by on December 08, 2016

Cranking the engine straight off creates NO SPARK. If I leave the ignition on for a full 10 minutes, the engine fires healthily with no sign of trouble at the first crank. The engine runs smooth after starting and never stalls. What could the fault be, please?

My car has 50000 miles.
My car has an automatic transmission.
