    D5K fuel regulator question

    I checked the tank right out the gate and even put my own source of fuel to the filter housing to eliminate the tank and the fuel lines. The filter housing has also been replaced with a new one. No codes just rail pressure is all over the place by thousand of psi compared to desired pressure.

    D5K fuel regulator question

    I got a question for someone that works on these more than me. I got a D5K LGP YYY01549 that has the 4.4 Acert in it. It started cutting out when you throttle it up and continues to cut out and puff black smoke as it catches itself. Rail pressure is all over the place so I replaced the return...

    Volvo A40D no communication with ECM's not enough power to pull a hill

    Thank y'all for the replies. I installed a new oil lever sensor and installed a new keypad so that I could change the screens and view the gear status. It does switch gears all the way to 6th as you said 2C-2L etc. I am able to switch from low to high no issue. High starts in 1st, low starts in...

    Case CX60C 9 pin connection location

    If anyone ever runs into this, it is not a 9 pin connector like the skid steers. It is a yanmar connector that is under and behind the ecm zipped tied to a set of wires. I had to remove the seat and the back panel to get to it.

    Case CX60C 9 pin connection location

    Hello all, I had a customer drop off a mini ex Case CX60C that needs a forced regen. He left it running all night at idle on accident and came back the next morning and it was way past the third stage manual regen. I have a computer with all the cables but I can not find the 9 pin connector on...

    John Deere 120C timing advance

    One of them has a new wiring harness installed by a deer tech. I checked it when I first started working on it. It was also having fuel derate codes due to excessive return pressure. The lift pump had failed and low fuel pressure killed the injection pump. I replaced the worn fuel system...
