Volvo Penta 5.7 GI No start

[FourWinnsLC]

Boat sat for a week, no start at the launch. Made sure it was in neutral, checked kill switch.
boat will turn over with no fire.
Changed fuel filter at the ramp, and checked the fuel pump fuse.

when I got home, I checked for spark and have it, I don’t know how to test if the fuel pump
Is working. I don’t have the pressure tester.

fuel regulator was taken out and the screen was cleaned.

what should be my next coarse of action?
