Disassemble and clean the carb. If it ran briefly with the starer fluid then gasoline is not coming through the carb.
SOURCE: pump loses pressure after you use it a while even
looks like you need a new diaphpragm in the pump unit
SOURCE: NO PSI
have you checked to make sure that keyway is installed between electric motor and pump. also adjustment on unloader valve may be incorrect. If the big brass nut on the unloader is able to be turned by hand, then this is probably your problem (running pressure and spike pressure needs to be set and locked down using a pressure guage). does water come out of nozzle at all? if not, tip being stopped up may be the problem. trash between unloader ball and seat can also cause no pressure (usually caused by a burr left inside brass pieces during the manufacturing process). I have seen all the check valves stuck on a brand new unit from sitting on the shelf for so long, but this is usually the case with General Pumps.

Hi:
You need to find the bypass (unloader) valve and grease it with a good waterproof grease. Sorry, I cannot find a pic for you

Being petrol driven, it may have a mercury kill switch which puts a ground on the ignition circuit stopping the engine if you move it. Perhaps for safety in case you overturn the unit somehow.
