Has anyone experienced starting problems? I have an intermittent problem as follows; Sometimes there is a 1 or 2 second delay between turning the key and the engine starting. At other times, when you turn the key, the warning lights come on, the fuel pump primes but the engine doesn't turn. Removing key and trying again, often several times doesn't help. Have tried combinations of pressing clutch and brake pedal and locking/unlocking car to no avail. After a short delay, car then reverts to normal behaviour. Dealer can't replicate problem but reoccurred on way home from garage. Suspect related to start/stop system. Any advice appreciated.
