injector problem

[squbafreak15]

ok so im still having problems with my injectors not firing.

they have fuel going to them.
they have signal
they click
but wont spray fuel.
every now and then when im swaping them out one or 2 might spray but then they will stop. what would cause this?

also from my understanding if its clicking then it should be spraying correct?

btw its a s2 rb20

Check if the fuel lines are backwards. The one coming from the filter should NOT go to the regulator.

pretty sure the lines r correct.

could it be tht the regulator is bad?.
how could i check this?

I have this problem with my #4 injector on my KA, sometimes itll work sometimes it wont.

last week 2 injectors were firing. so i ordered 4 more. they came in yesterday and i went and turned the engine over so i could see which injectors weren't working and none of them were working. so i put the 4 new ones in and one of them sprayed for a few min but now it doesn't either. they just click

i have a feeling that maybe the vacume lines not being hooked up all the way might have something to do with it.

im using the same pic as earlyer
i drew in were i think the lines go but im unsure.

where does the vacume line that i highlighted green go?
