[DML] Fuel Pump or Not Fuel Pump?

I am a two-week owner of an '82 DMC, VIN 10820, 11K miles from an
owner
who reportedly replaced lots of things from 3K miles on including the
fuel pump, lines, filter. I figured I might get some time driving
the
car before something went too wrong. HA!
That said, I think the honeymoon is over and it's initiation time. :)
Went to start the car today. It fired up and stalled about 3 seconds
later. Engine now turns over strongly but does not fire.
Removed the air filter and dropped a few drops of gas into what would
have been the carburetor in an older car (I'm not a mechanic but it
seemed fuel mixed with air here might do something). Engine started
immediately and ran a few turns until that gas was exhausted... a
second or so. So I seem to have ignition capabilities but no fuel
where it is needed.
Poked around on the 'net and in the shop manual that came with the
car.
Here's what I've seen so far:
Fuses 1 and 7 appear to be related to the fuel system. They are
intact.
Impact switch is in the proper position and cycling it did not make
any
difference. Contacts do not appear to be corroded.
Located the RPM relay and removed it, inserted a by-pass between
terminals 30 and 87. The heavy paper clip I used gets warm but I do
not hear anything from the direction of the fuel tank (the fuel
pump),
even with the ignition key "on."
This done, I'm led to believe the fuel pump is not running for some
reason not listed above. I have located the fuel tank but don't want
to
go diving in there to inspect the fuel pump with nearly a full tank
of
gas.
Questions:
I'm assuming the rubber boot over the pump should not be removed with
gas in the tank but let me know if that assumption is wrong. This
part
appears to be pretty dried out and should probably be replaced.
Any other diagnosis I might be able to do to confirm the pump is dead
before I order one?
How do I get the darned gas out of the tank if I do need to change
the
pump?
Thanks for any and all help!
