There are several causes of hard starts hot.

The above can all cause the problem, but you should also take a look at the condition of injector seals, idle control valve hoses, and the boot between the fuel distributor air horn and the throttle body.

Air leaking in that does not go through the air meter venturi will cause hot start problems, typically a start and immediate stall (extra fuel when cranking). If you also have rough idle or variable idle speed, check for vac leaks (including all the vac operated things like climate control and tranny shift modulator. Occasional stalls while decelerating, especially abrubtly, are indicative of a leak.

If it is otherwise running well, suspect a bad accumulator -- this will permit vapor lock.

A bad fuel pump relay and/or bad over-voltage protection relay can also cause hot start problems -- the hot relay is intermittant, and you have either no fuel or no ignition momentarily. If you have occasional stalls while driving, it's the fuel pump relay or pump
