    Same motor. The AMI's were Maxidyne and the AI was Econodyne. Different programimg for HP/torque curves. The AMI's seem to made their HP at a littler higher RPM's . At last thats what I can tell by the charts.

    Mackpro replied to pnil m's question in Mack Truck Q & A

    Best I remember they had a little triangle shaped support strap that bolted to the top of the water pump housing over to one of the head bolts that was threaded. Thoses straps broke and or were thrown away over time. Without the support strap the weight of the fan clutch and belt tension would break the water pump housing.

    25101415 is the new part number, the old part # was a 64MT450A

    I this it's called " Customer Defined Software " . We have run into some ABF freight trucks that all the parameters were burned into the ECM's. My buddy bought a ABF 2002 CX and when I went to raise the road speed, it kept going back to 55mph. We finally callled the tech support guys and found out about "Customer Defined Software ". We had to do a total reflash of both of ECM's and this solved the issue!

    After looking at 2 different charts I have found on the CCRS engines, Some 350's and 400's used different turbo part #'s. However some used the same. Turbocharger part numbers.pdf

    I found the SID 230 in the book. What year/model of truck? 2008 MID fault codes.pdf

    With early 98 through 2002 ETECH engines , the only difference between 350 and 400was the program. However Mack wanted us to install a larger vibration damper if the engine had the smaller one on it. Being yours is a 2002 it could have either the ETECH or the CCRS style engine in it. I believe the CCRS engines were like the ETECH and the 350/400 used same everything but programming.

    A few months ago I posted the Mid and SPN fault code list for 2007 up to 2013 MP engines here . Some time in 2014/2015 they started using the P****** code listing. Due to Mack /Volvo trucks , after 4 o'clock on Friday I find myself far away from the Internet and class 8 trucks in general. Lol. Hopefully the search engine works and you can find what I posted and your fault listing is in there. What is the MID ?

    For an auto trans, one wire is grounded and the other goes to gauge. VMAC2 MR scan0497.pdf

    Shoot air directly into actuator and see if arm on turbo goes down. Only apply 30-40 pounds as not to blow diaphragm. There is instructions on manually adjusting actuator rod on a VGT turbo but I can't attach the bulletin at this time

    Snap on part # GLD139 if you got money to blow! LOL

    I have seen starter draw to high and pull voltage away from ECM and cause crank no start. Check volts at ECM durning cranking. Needs around 9.5 volts min to start.

    If you ever get th ECM to power up. There is a big cap nut on the front of the fuel pump that faces the fan . . It is 1 " or bigger. Remove it and stick your finder in the hole. Turn key on and push throttle pedal to the floor, you should feel the rack push your finger .

    I forgot, being a 96 it's a VMAC-2 with 1 ECM. I have attached the VMAC-2 troubleshooting service manual but sadly there is no "Crank no start" troubleshooting info in it like the VMAC1 and 3 manuals. It does have some ECM info in there though. VMAC 2 manual.pdf

    Jump across the big solinoid in the fuse box ( assuming its a pre-ETECH truck). That should power up both ECM's

    Looks like DPF Diff sensor showing high soot, Look at MID 128 PID 81 FMI 12 2008 MID fault codes.pdf

    If you can't shut off engine and the throttle pedal won't work and your idling at 900 rpm , the vehicle control unit VECU has lost coms with the engine ECM on the 1939 data line yellow and green twisted wires

    Install some coolant shut off valves on the heater hoses on the engine if you don't already have them, it should help a lot.

    Part # is 243AX6F

    It's push on fuel return line. The very early 98/99 ETECH engine has them coming off the back head. They later moved the fitting to the front head.

    I remember replacing lots of the copper pump washers on the early Robert Bosch pumps. The new replacement washer was steel. I still have the socket for it. The later pumps had no washers at all
