need help figuring out whats wrong

[1jzz30]

ok, let me give you all a run down on what set up I have then I'll move on to the problem.
Power FC
Precision 75lbs injectors
mk3 resistor pack
aeromotive fpr

the problem is only injectors #1 and #6 are working as the car starts and idles.
I thought there may have been a short in the signal wires for the injectors so I cut them at the ecu and ran new temporary wires. I seem to be getting a 12+ on both sides of the injector connector. but the same signal wire at the ecu is 0v. do you think its a bad resistor pack ? or 4 of the new injectors are bad ? I know injector #3 and #5 are on the same signal wire from ecu and #2 and #6 share a different signal wire at the ecu so I dont think its the ecu
the fuel pressure is are 45ish.

and a visual inspection of all the coils/plugs sparking was also done.

I swapped the injectors and get the same result.

I also bypassed the resistor pack and still got nothing.

Even if the noid lights I made come on could it still not be enough to get injectors firing ?

Also maybe IM not doing something right or missed something on the Power fc for these after market injectors


Thank you in advance !

Power FC is a stand alone right?
Have you selected the proper settings in the FC for your application?
What type of injector firing are you using?
Can you draw the injection circuit you used and post it?

the Power fc is indeed a stand alone. however it isn't universal I am using the one for my application (soarer). Im using precision 75lbs injectors low imp wired thru the MK3 resistor pack. The resistor pack is wired the same as it was before the injector and ecu upgrade.

I would un-plug the connectors from the injectors and check continuity back to the ECU to check the wiring.

How do you know only 1 and 6 are firing?

not sure if you noticed on my first post. I checked the wired from injectors to the ecu and even cut the wires and replaced it with temporary wires to the ecu to make sure there wasn't a short.

I know those are the only injectors working because the car idles rough and no change occurs when I pull injector plug 2-5 and dies when 1 or 6 are pulled
