Hello,
I’m looking for some guidance on diagnosing an issue on my 2002 TJ. The Jeep struggles to start and when it does start it runs very rough. I get huge clouds of thick blue exhaust and it smells like it’s going to explode.
My code reader gives me p0203 code, “Injector Circuit/Open Cylinder 3”. I figured that the number 3 injector was stuck open and dumping fuel into the engine causing the issues.
Now I’ve got the Jeep home finally trying to fix it. I tested the resistance on the injectors, they all seem about the same. I tried putting power via a 9V battery to the injector connections and they all appear to cycle fine.
Not sure what to do now. I figured it would just be changing injector# 3 but now I’m not so sure. Is there a way to check if the injector is receiving the proper electrical input to cycle correctly?
