Ficm voltage question...67-68 volts?
Hello all. I'm working on my 05 truck right now as it has finally quit on me. I went to start it first thing in the morning, and it started as usual. It has sticky injectors so it's always a little loopy on start up. After that I went to get fuel, same place I always get fuel, and I started it up again. No problem. Then about 2 mins later as I'm driving down the street, I look out my mirror and notice its smoking blue more than normal. So I let off the pedal, and it's still smoking. When I got to my buddies house, it was now a mosquito fogger at idle, and when I tried to give it throttle, it just loaded right up. I was about a mile from home and barely made it.
When I had time to look at it, I suspected a stuck open injector. Or a turbo seal, or ficm. So I checked the turbo, and it was all good. Pulled the glow plugs and none of them seemed to spew out gobs of diesel. So I also tested the ficm and it came in at 67-68 volts KOEO and while cranking. I have never heard or read about one being too high. Is that possible?
