    VMAC 1 Fic is the bosch module ! Your issue will likley be with the VECU the aluminum one! it gets all the vehicle inputs ! and talks to FIC and tells it what to do!

    Yup I agree Joey start with the cheap and easy ! It was just an honorable mention at the start there! That said the miss for a push tube would likley be accompanied by a ticking noise the stumble maybe a clue as well! crack some fuel lines and identify which cylinder it is and start by checking the valve set!

    Not always But a possibility ! is the truck drivable ? do you have a local fuel shop in your area? it requires a special socket to remove the delivery valve!

    K three cylinders different heads is weird your injector thery may be the next thing maybe have em all tested !🥵 Just to rule it out! Or in!
  12. fjh
    Does the truck have engine brake? In plug for now at the valve cover!

    👍 either or switch /sender will derate him I know for a fact that torque limit wires rubbed together is a 50 percent cut! Had to chase this once!

    Its relatively easy to get the floor out why not pull and trace that section anyway! pull the hatch Lots of room to look then long as there's not controls bolted to it!

    if it looks like a duck and smells like a duck just saying! Nail the cylinder down my! suspicion is a bent valve or valve train issue! ! Lack of compression! or a bent rod! But You say it smells like raw fuel ! You could have a sticking injector I suppose! can't hurt to have em pop tested ! or nail it down and swap em! see if it perks up on the dead cyl! relatively simple DYI stuff cheap to do! Just me!

    so don't ask any more questions of him! I know what its like to have someone breathing down your neck! Make sure he replaces the bolts and make sure to get the cal numbers off the new pumps and their locations if he doesn't have the Mack soft ware!

    So just a comment on this ! If its a ROBERT bosch manual pump (likely is) identify which cylinder likely number 1 The delivery valve washers are made of copper these have been known to crack and leak by internally ( specially on number one) and cause a miss most noticeable At Idle! Crack fuel lines at the pump till you find one that doesn't change the sound of the engine that will be your culprit ! just something to look for!

    Good Find and good info Bro! SO , Is this the same as the trim code? or some other function In PTT!? Learned Data Reset? Just askin!
  20. fjh
    Yup and if you insist on changing pumps use new bolts to install! also you need to install Cal codes into the computers brain if he doesn't have the VMAC 3 software on his lap top you my need to go to a shop that does so write down the numbers off the pumps and there location so it can be done!
  21. fjh
    Correct Heinz Just making a point! It does make sense what JoeH stated there how ever they used ATF for years with a direct couple pump with out issue! I think the purpose was monetary at the time! quick and easy and cheaper! Just sayin!
  22. fjh
    The ps pump is engine mounted on mp engines as well I believe are they using engine oil too? just sayin!
  23. fjh
    Can't help there! Sorry! Joey you got a wiring chart?!
  24. fjh
    👍

    Agree Heinz! re check the set! How ever Fuel knock is pretty distinctive! Harness is a good probability it should be coding out thou! or pin fretting was a common issue!
