The vehicle starts fine when cold, and will run well until it is turned off. When it sits for longer than 15 minutes it will not start. It cranks and tries to start, but does not catch. I have replaced the IAC, and PCM relay. I have not checked the fuel pressure yet. I have also replaced the fuel filter. Any suggestions?

Hi dfburi1,

Thank you for the donation.

Yes, checking the fuel pressure is the next option but before doing it, I would suggest testing the sparks when it fails to start. Sparks should be bright blue.

Apart from that, if fuel pressure and sparks looks good, check the Engine Coolant Temperature sensor.

Does the Check Engine Light indicate while driving?
