Try loosening the bleeder by the nameplate on the pump..
U need a 5/16 box end wrench..
USE THE BOX END..
It’s a double screw.. loosen up the 5/16 portion and crank the engine..
It should shoot a stream of fuel a city block.. lol. but seriously, about 3ft.. if it does, GREAT.. tighten it back up SNUG.. not cheater bar tight..
Now loosen ALL the steel injector lines.. put the throttle wide open and crank till u get fuel up there..
Don’t burn u the starter trying.. if it doesn’t show fuel pretty quick, stop.
IF it doesn’t squirt fuel at the bleeder, that’s bad news and u gotta call a wrecker to get u back to the shed..
