Cummins 260 hp, ISB diesel, 5.9 - 2001 model

Stopped at a road side for a break and when I restarted I pulled onto the highway but with only 25% of the normal power. Turbo boost is between 7 & 8 lbs. No sound of loss of turbo pressure. Engine kind of surges when trying to accelerate like its starving for fuel. On some of the surges I see some black smoke, just a whisper. Replaced the fuel filter and didn't help. I'm in Moab UT and would you believe that there isn't a single working diesel shop in 130 miles of this place??? A couple of mechanics (?) have knee jerked diagnosed the problem as the fuel pump. I can drive 130 miles and pick up one but they need my engine serial number. Any idea as to where that is located? Its not part of the Chassis ID Data or any other tags on the body.

    Try this for trouble shooting.

    turn the key to the on position, have a listen to the engine compartment. there should be a pump running, wait 3 minutes see if the noise quite.

    Cycle three times and see if the problem goes away.

    Just me but I would join http://www.turbodieselregister.com/ post and read there instead of throwing parts at it. And if it is the fuel pump I would go with a FASS system. That is what I did and I'm very happy. Just the ease of changing filters and water separator is worth it to me. Parts are to expensive to change out without knowing for sure what problem is. Nothing better than taping the experts on-line when your stuck in middle of nowhere. Whatever problem is can't be to bad. That year is almost bullet proof with right trans behind it and proper care. IMO
