Hard starting when car is hot?????

[JMINMD923]

If I start the car after it has been off for just a short while it is hard to start. If it is off for a long while it starts fine.

Any ideas?

fuel filter? worked for me with the same issue.

You could buy a fuel pressure gauge and hook it up to the test port and see if there is a different pressure in the two situations. Maybe somebody with more experience will chime it but I think the fuel pump relay can also be a problem. I think there is a stage 1 and stage 2 for the pump but I don't know if it comes into play during starting.
