Ok guys I have a kid at school that wants to trade trucks an had me look at it for the p0093 code. I checked the rail pressure and at WOT on the tech 2 it's only getting 16-18k so I looked at the FPR and it's only going down to 10%. Injector balance rates are not over 4.0. Is this sounding like the FPR is bad? I didn't get a chance to unhook it and try running it.our duramax has never given us any problems and I've never got to mess with one that has this problem. I just don't think I wanna trade if it's gonna end up being the cp3.
