Hard start when hot

[ninetyfive]

If I get to temperature and park the car, after 15 minutes it starts right up, but after 30-40 minutes it takes it a good seven seconds of cranking. Starts up right away when cold. Fuel regulator was replaced last year.

Any ideas?

Check fuel pressure drop-off and boil-out with a gauge. If it tests OK, what you describe is also a symptom of an impending PCM failure. They start to become erratic when the module gets warm.

If signs point to that, DO NOT TAKE LIGHTLY. G1 modules fail catastrophically in most cases, and the cost different between a partial reman and a total reman + invalid core is thousands different.
