After having parked for 2 to 4 hours, the car starts and dies within 10 seconds. After that it does not start even after 5 or 6 tries and then it starts again and dies immediately. Fuel pressure checks out good . It am assuming ignition system is working good because when it starts engine runs smooth. However, I did not perform any checks on the ignition when engine does not start. I would definitely check that out but is there anything else like sensor or relay I need to check too. Appreciate your help.
