My car has trouble starting after it is warmed up. Could this be a bad fuel pressure regulator?

I have never seen an FPR fail on a honda. Your problem, if you are not getting fuel after it's warmed up is most likely your main relay. If your main relay is fine, have a look at the fuel pump

Speaking about the main relay, been there before with a 98 Honda Accord-DX and got me good-between it and the ignition switch-No fun
