Installed new fuel pump. Vehicle started 10 out of 10 times last night. This morning will not start and has not started all day.

Welcome to the forum, if you think fuel pressure is the issue, use a gage and check fuel pressure. Any trouble codes? Engine cranking, did you visually check for spark at the plugs?

Can you tell if the fuel pump is trying to work?
