My 98 4.0L manual usually starts right up, even when not driven for a few weeks (it's not my DD).
Over the last few months, I've noticed that it has to crank much longer after a drive, say 40 miles.
Runs and drives great, but when I turn it off, let it cool, and come back a few hours later, I've had trouble starting. It cranks strongly, but seems starved for gas, maybe.
I had the fuel pump replaced in 2012, but am I now having trouble with that fuel pump check valve I've read about?
Shouldn't a new fuel pump have solved this, or should I expect to have to replace it again? Should the (very reputable) shop that replaced it be responsible for fixing it?
Thanks!

A few hours would rule out vapor lock. What happens if you restart after 10 mins?

Usually if I'm running errands around town, it starts right up every time. Seems to be the long drive and complete cool down that causes trouble.
However, if I come home from a long drive, and come back to it a few days later, it starts right up.
Unpredictable, and I'm worried I'll get stranded somewhere remote, unable to start.
