So the ranger I have has a ECU problem occurring not firing one of the fuel injectors. The part number I have currently for the ECU is 4017498, my question is what ECU would interchange with this ECU, only part I’ve been able to find online is the 4014125 ECU. Is this a direct replacement?

Only one injector fires until it starts.

Only one injector firing while the engine is running. Have checked wires going to ecu and they are good. Also confirmed that both injectors are good by swapping them and problem stayed on the same cylinder. Only thing left is the ecu that I am aware of

4014125 is correct. it's raw ECU without any program on it. you have to get it programmed to match your ride. I'd send it to Gilomen Innovations to program and tune.
