No start, cannot hear the pump turn on?

Can't hear fuel pump run, no fuel pressure, cranks great but no start of course.
No access panel in the van, hard to trace wires. The only wiring diagram I have found so far is for a 2006 and I don't think they are the same. Digital VOM reads ' OL' when checking ground continuity.
Not sure if I'm checking correct pins, due to a diagram for a different year.
Working on it in a gravel driveway, not looking forward to dropping the tank if I can get out of it.
Relay and fuse are good.
Van belongs to an older, disabled person with below poverty level income and has been run low, low and out of fuel several times. I'll buy the parts and do the labor, but don't want to mess it up worse. Semper Fi.
