One easy thing to check in regards to the pump: If you turn the key on to the "run" position (but not the "start" position), should should hear both pumps run for a couple of seconds to prime the fuel system. That can at least tell you if the electrics are working. From behind the RH seat, you should hear one hum, followed by a second, and then both will stop as it runs the primary and secondary pump.
The in-tank hoses are connected via a Y, so if you get a rupture in those hoses, you should show a massive drop in fuel pressure. When that happened to me, the car had 0 pressure and there was no chance of it starting because the pumps were just putting all my fuel pressure back into the gas tank.
Before you go pulling the pump, you can rent a fuel pressure gauge for free from the parts stores. Just screw this on to the RH fuel rail and turn the key on a couple times without starting to make the pumps run. If you are getting much less than 55 psi, you've got a problem with the fuel pressure. (Section EMM.3, page 10 in the manual)
If you have to remove the pumps for repair, you just remove the RH carpet panel adjacent to the engine bay, wedge yourself in there, curse many times, unplug the electrics, remove the retaining ring, curse, and then pull the pumps out. Installation is in reverse with a little more cursing added. No need to remove the engine or anything other major component.
Obviously, you are dealing with fuel under pressure, so the usual warnings about gasoline, ventilation, heat, and fire all apply.
