I've got a M931A2 with 8.3 CTA and it won't start. I replaced the fuel transfer pump and I've got good fuel pressure to the IP fuel inlet line. I've also changed the electronic fuel shutoff solenoid and that didn't help either. The truck does fire just fine with a shot of either. Do I assume at this point that I've got a bad injector pump? Are there any electronics, other than the fuel shut off solenoid that would cause the IP not to function properly? The NHC250 Cummins has a manual override knob on the fuel shut off mechanism; does the Bosch pump on an 8.3 have anything similar to that? Thanks for any suggestions. Joe
