I just bought a Kenworth t800 with a Cummins M11 330hp. I bought it knowing that the ECU was bad. So i took it off and had it rebuilt. The truck is doing the same thing that is was doing before hand. It will run off either and it appears like it is pumping fuel. Strange thing is the filter is only about half full (it has a steel spin on filter) after running the truck on either. There is no hand pump on the motor so i would take off the filter and fill it up, crank it and check the filter which is half full at that point. The injectors are under the cover so i cant crack them to eliminate that. However when you crank it and crack the line at the injection pump it has good fuel coming out??? So i guess that tells me there is something electrical stopping the fuel or there is a check valve stuck somewhere?? I have no experience with this motor so any guess would be helpfull
Thanks!!!
