Before I test the injectors, I pulled the fuel head to clean it out. It’s actually in decent shape inside and the slit o-rings look okay and piston moves pretty smoothly with the spring in there. That being said, the diaphragm is pretty beat up. (Check picture of Swiss cheese) Could this be caused by a bad diaphragm leaking fuel to the injectors? I guess I would have expected the pressure to be all off in that case. I know there’s no official rebuild kit for these things but I have an ultrasonic and I cleaned the head. Need to figure out what to do about a replacement diaphragm.
If I’m on the wrong track, I’ll put it all back together and pull and test the injectors. Not looking forward to the intercooler side ones haha
