Not really, but if it stopped then it's likely nothing to worry about.

No real tricks, just the usual investigative work.  Are you sure the shutoff
valve is open ?  Sediment bowl and gasket installed on the pump and
tightened up ?  Fresh fuel in the tank ?

Being a risk taker, I'd probably start by disconnecting the soft inlet line
between the valve & pump and seeing if I could suck gas through from the
tank.  If you're a more cautious sort, you could use a Mityvac or similar to
do the same test. (HF has a nice unit that is sometimes on sale for $20

If you can pull fuel from the tank (through the valve), then my next step
would be to disconnect the line at the carb inlets and see if the pump will
push fuel through to there.  If not, check again at the pump outlet.  Then
if all indications point at the pump, pull it off and bench test/repair/etc.

On my "barn find" TR3 project, there proved to be multiple blockages.  DPO
had installed some unusual kind of valve in place of the original, and it's
innards apparently dissolved into silly putty.  Which in turn gummed up the
pump valves, and float valves.  Haven't been into the pump yet to see if
it's salvageable, but the other blockages succumbed to carb cleaner after
some fiddling, and the temporary electric pump was able to supply the carbs
for a few seconds of operation.
