intermittent hard start/no start

[sponge]

car is a 2002 3.4 with ~120k miles

only when car is hot, sometime will crank long, or it will take a few times to actually start. always starts right up every morning.

recent maintenance includes fuel filter, air filter, cleaned maf sensor, oil change and filter, pcv valve. i have no fuel pressure gauge, and i'm suspecting a failing fuel pump. what should i do?! any suggestions appreciated!!

edit: no codes at all!
