Hi, I have had a on-going hot start problem. I have changed the Thermo Time Switch which has improved things and the Air Aux Valve is working. After 1-2 hrs the car still starts okay but after 4hrs it is taking 3 attempts. I have been advised it may well be the Hot Start Pulse Relay. I'd like to change it. Can you advise where this is located on the car? Much appreciated.

Hi may I suggest that you try adjusting the throttle butterfly till it closes . Then 1/3 (recomended ) -1/2 turn . No more. Go drink a beer and try it later . It isn"t a hot start after 4 hours.The hot start relay should be in the relay box closest to the radiator if it has one .
