they told me the bull gear??? ( I think that is what he called it the fuel pump that feeds the rail) was weak and I had cavitation in my fuel and i told them to replace it

A. there is no "rail" on a CM870 (or CM871). it is an IFSM --> https://youtu.be/MWiSwgcwIoc

B. If the gear-pump has problems, it would simply be low fuel pressure. Easily seen in insite by monitoring fuel pressure. 265~ish to 300~ish is normal pressures. If you suspect air getting into the fuel system then pressurize the fuel tanks to 10 psi and let it sit for several hours/check for leaks.

C. The proper method to test the fuel system, injectors and actuators is to...
-- Adjust the overhead valves to ensure the correct crush prtessures are on the injectors.
-- Do a injector leak test ... https://youtu.be/Wu_WN8BA-LA
-- Then perform a cylinder cut-out tests, running the entire engine on only one cylinder at a time ... https://open.lbry.com/@rawze:d/isx-injec...e-cm2250:e
After that, if you suspect worn out actuators -- TAKE THEM APART AND INSPECT THEM>>> http://rawze.com/forums/showthread.php?t...619#pid619

A complete crock of horse-sh$it!. - Sure, you may have an active code in the ecm for the lift pump not being connected to it -- BUT IT HAS NOTHING WHATSOEVER AT ALL to do with re-flashing the ecm, or updating the software in the enigne. the ECM would simply still have the code after the update/changes. -OR- did they say the lift pump itself has software in it? -- that would be an even bnigger crock of sh$it... it is nothing more than an electric motor/pump. Either way <-- LIES and MORE LIES and -- > a complete bunch of fu#$ktard morons!. --- RUN LIKE HELL AWAY FORM THEM -- AS FAST AS YOU CAN!

^^^ Did they do all the steps mentioned above to determine this? TELL THE YOU WANT PICS AND/OR MEASUREMENTS OF THE EXCESSIVE WEAR IN THE ACTUATORS BEFORE YOU PAY THEM $$$$$ FOR NEW ONES!... -- I HIGHLY DOUBT THEY EVEN CHECKED THEM! <--- AGAIN --> a complete bunch of morons!. --- RUN LIKE HELL AWAY FORM THEM -- AS FAST AS YOU CAN!

-- Sounds like they are trying to sell you one of those redneck hack-job internet-rambo deletes that repeatedly destroys engines and turbo's + trying to "upsell" you on a non-vg turbo and after-market manifolds -- THOSE ARE THE WORST OF THE WORST STYLE OF COMPLETE BUTCHER-JOB DELETES OUT THERE BY FAR!!!--- HORRIBLE CRAP WITH REPEATING ENGINE FAILURES + ALL KINDS OF OTHER PROBLEMS -- GETTING DUPED INTO SH#IT LIKE THAT IS LIKE DRIVING DOWN THE WRONG ROAD IN THE WRONG NEIGHBORHOOD AT 3:AM AND REGRETTING IT GREATLY -- AGAIN -->> a complete bunch of fu#$ktard morons!. --- RUN LIKE HELL AWAY FORM THEM -- AS FAST AS YOU CAN!

If you want it de-mandated correctly without all the hack-job butchering, get with Mommaburt, Unilevers, or Mr.Hag.

THERE IS NO COMPUTER SOFTWARE OR TEST THAT CAN DETECT LINER ISSUES !!!-- WHAT A CROCK OF COMPLETE HORSE-S$IT ---->>> Pressure test the coolant system to see if you get rapid buildup on a test drive or during heavy engine braking. -- AND/OR-- Drop the pan and pressurize to 20-psi and let it sit over night -- THAT IS THE ONLY WAY TO KNOW IF YOU HAVE LINER ISSUES!. -->> a complete bunch of fu#$ktard morons!. --- RUN LIKE HELL AWAY FORM THEM -- AS FAST AS YOU CAN!

TEST IT PROPERLY --- STOP GUESSING AT IT LIKE A DUM,BARSSE!!!! -- TAT IS WHAT I WOULD HAVE YELLED AT THEM WHILE I WAS DRIVING AWAY AS FAST AS I COULD!

yup!

AGAIN--- WHAT A CROCK OF sh$it... pull them apart --- DO THE PROPER TESTS ON THEM !! check them for excess step wear as mentioned above.

I can only hope maybe you mis-understood these guys or something,.. Surely there is not a shop out there THAT F#KING BAD~!!! -- But then again--- I know of several that are this bad or worse yet. -- It is a complete damn shame that truck owners and drivers who don;t know any better get raped up the arsse by clowns like this and shops that are this twisted and crooked out there in our industry. -- Makes my stomach hurt thinking about it.
