Re: 4.3w poppet nozzle,Tryin to get to open
First thing disable the coil so it will not get spark to plugs or it will self distruct when you crank it.
Just gas at test port will not get it.
To get the fuel injector to squirt you have to have full fuel pressure. not even 2-3 lbs low.
If you have full fuel pressure and injector pulse to injector unit then crank it and the injector nossel should squirt out gas.
It will not pour out but should shoot out a fine mist.
Also them pressure and return plastic lines look kinda brown. If they have not been replaced now is the time to do it.
What was the reason you pulled the upper intake?
