Help! S13 Sr20det 4th injector won't fire

[kylaris]

I have S13 sr20det BT. The problem is the 4th injector won't fire.things i've tried-checked the injector ohm reading. they are same across all 4-check power on the red wire. Reads battery-Check continuity to ecu pin #112 and it's okay.-Tried different ECU

Those were the things FSM told me to check and they were all good.Any other things i should check?

you could try to swap the injector the another cylinder and see if its the injector and go from there.

Agree with Joe. Just had the same issue. The resistance across the injector was the same as the other three, jumping power and ground on the injector gave a very weak "click," swapped it out with another injector, all's well, haven't looked back.
