i have a 1998 nissan maxima with a 3.0 engine. When it is running it will fill the exhaust full of gas. I have changed the fuel rail and injectors, No code lights come on. could a defective pcm cause this problem?

I would install a fuel pressure gage and see if you have a injector leaking or o-ring seal , if no leaks then the ECM could be shorted and causing the injectors to stick open if grounding it can cause injectors to hang open, Thanks let me know if you have more questions, ROY!
