We have been at this truck for weeks now. I bought it about 3months ago and it just sounded like it needed new injectors. In the last 3weeks we have replaced the injectors 3 times because it keeps sounding the same. Its a constant misfire whether at idle or acceleration. I pulled the codes with my scan tool and its giving codes p0193, p0113, p0237, p0069, p0483. Also it says fuel rail pressure relative to map. We have checked over and tested the wiring harnesses and this is what we have come up (truck in run position) the fan has 5volts, the cam black/blue 35ohms tan/yellow 5.1v grey/black millivolts, map sen shows 5volts on feed wire the ground was within specs but the signal wire had 5.1volts. Is the signal wire supposed to have 5v @ map sensor and is the signal wire to cam sensor supposed to have 5v to? Any ideas I will appreciate. I'm at a loss right now. It is a 07 5.9 Cummins Thanks
