I agree with Dick that it sounds like an electrical
problem. But....
If you confirm that it is not an electrical problem,
TR's have been known to plug the fuel supply line
from the tank. If all else fails remove the supply
line from the pump, open the gas cap and blow some
compressed air from the pump end of the line to the
tank. If there is junk there this should knocker loose.
FWIW
