No start on Engine
On my 345 the engine will start and run for a short time even with no electricity to the rear fuel pump, which is not internal to the tank, but mounted just forward of the tank.
The mechanical fuel pump, on the foreward curbside of the engine, will pull fuel through the electric pump, as Peter indicated, but not enough to maintain speed.
A total absence of fuel in the carb could be caused by a clogged carburator filter. This filter is internal to the carb, located at the fuel line inlet fitting.
Of course, there could be blockage anyplace in the system.
If it were me, I would validate rear electric pump performance (changing all filters and deteriorated rubber as lines are separated to confirm fuel flow), and work forward.
All this takes a while, and be prepared for some surprises.
