C-121 fuel pump.

now the WH run last time i fired it up but today it wouldn't start took spark plug out and it was dry. so i pull the pipe off the pump to find its also dry. with the pump off the diyafram looks to be ok no holes that i can see. does anyone have any ideas? i think possibly it could be what hits it inside the engine?

How long has it been since you have run it. You may have just lost prime to the pump and it wont pull fuel. Put it back together and dump a little gas in the plug holes and see is she takes off.

first thing i tried when i seen it was dry only got one bang. this time going to try putting some threw the whole line with syringe like when i do my bike brakes. thanks for that idea! more fuels more bangs!

Have you checked the shut-off valve and screen for a blockage?

I use a spray bottle with gas in it and pull the air filter off spray in carb till she runs

Pull the fuel supply line off the pump and see if gas runs out freely there. You could have a problem ahead of the pump. If the gas runs freely then reinstall the gas line, remove the fuel live from the carb and engage the starter for a few revolutions to see if it pumps fuel. If it does not, then you know what to do next (replace the fuel pump). If it does pump fuel then the carb needle may be stuck in the seat. This would not allow the pump to move fuel into the carb. Todays gas can cause the needle to stick in the seat if the tractor is left unattended too long.
