    these are the controllers I found up in the dash. im not having much luck with the tests with the pump and computer. I might have someone else near by give me a hand with the scanner reading stuff.

    It's also likely that all that can throw the system off, giving those weird codes.
    But I wouldn't be surprised if the computer fried.

    I'm not for sure if those computers are intercepted the factory computer. You might be about to disconnect the and hook up the wiring back together if it's not hard wired in. See if you will fire or pull different codes.

    I did some more testing yesterday and talked to another diesel mechanic down the street. I took the fuel filter down to check that, it was pretty clean. I put a new one in and tried to use the electric pump to fill the rest of the filter and check for pressure. well, I got nothing. I took the pump out and stuck one end in some diesel and it wouldn't even pump that, so I think I found one problem. I ordered a new one and see what happens.
