There is no need to bleed air from a fuel pump.
Pop the bleeder and cycle the pump until only pure fuel is coming out.
If it is just one injector, it is a bad injector or a problem in the wiring harness or connector for that injector. If it is all of the injectors, it could be a fuse, the entire injector harness, a broken loose or unplugged connector on the injector harness, or the fuel pump or fuel pressure regulator.
it has throttle boddy
in the engine
The most common problem, when a 1990 Geo tracker floods out with gas, is a bad fuel injector. The injector might be leaking or injecting a steady stream of fuel
Fuel leak, or Fuel Injector stuck partially open.
the harness could be bad on that injector chech to see if its firing and if it is then the injector is bad
yesyes
you open all the injector lines at the injectors . Then pump the fuel pump primer on the fuel pump . fuel will flow out one or more of the injector line , close the injector line and roll the engine over until the next injector start to flow fuel and so on , why are you having problems
spark plug
you can see the valve on the fuel injector. it is on the passenger side of the car and to the front of the injector.
Injectors will self bleed when vehicle is "cranking" provided system is working normaly. The pressure regulator will bypass all extra fuel and return to the fuel tank providing constant fuel supply to injector.
