If the motor is hard to start first thing when cold, it sounds like your fuel pressure is bleeding down. I would check your fuel pressure regulator and injectors. Sure sounds like you have a bad injector leaking down, or regulator not working correctly, keeping the pressure at the correct level. Sounds like you have checked a lot of things out, but this area. Give it a try and see where it gets you. Good luck
