Hello and Welcome! I'm Billy and i will assist you with your inquiry. Feel free to ask if any further info is needed.
My apologies for the delay, thank you for your patience.
Did you check the wiring from ECU to the injector?
As the injector should get positive from fuse 24, and negative from the computer (ECU). If you remove the injector connector, do you still get positive on the ECU size?
Did you check this wiring, for any shorts (short to positive in this case)? or even tried running a new wire from ECU pin 103 to the injector?
