Hi. My problem with a ford falcon(australia) 4 litre 6 cylinder is the car starts first go when cold. After a few miles if you turn it off and then immediately restart there is no problem. If you leave car for abt 10 to 15 minutes the car cranks but take ages to restart and there is a smell of fuel.this only occurs when the engine is warm. Ron.

it's flooding out, often old leaking fuel injectors OR bad fuel pressure regulator. Try this video first https://www.youtube.com/watch?v=bKGI9N_yWd0&t=67s
