[CurleyMerkin14]

so its a rb25 injector 3 is stuck on its not the injector it self i switched it with 2 others and it still just stays on that cylinder also it comes on as soon as the ignition goes on ... like im not trying to start it i just turn the power on and SPLASHHHH that injector goes nuts anyone know why this is ?bad ground some where ... ecu went homo?

[CurleyMerkin14]

Re check the Wiring Harness

Yea just took the harness for the injectors all the way apart it looks yo be all good fallowed the wire to the ECU and it is also in good condition its just that one plug no matter with injector I plug it into it just blast fuel

come on guys!!! i really need help with this im pretty stumped

[VinceDude]

could be your actual ecu. I'm pretty sure if it's a fuse all the injectors would be going crazy so i don't think it's that. Could be your wiring too bad ground maybe(long shot)? If all else fails it's prolly your ecu but don't quote me on that.

Eliminate the wiring for that cylinder(injector): Depin at the ecu for the trigger ground, run a wire from the ecu to the problem injector. Do a KOEO verification, If that injector still has an issue it's the ecu!

Key On Engine Off

If you do pass that test, I wouldn't see any harm in firing it up!

sweet shit dude ! ran new wire to the ecu from the injector and POW! it works!thanks for all the help!
