Re: Cat 3412 E does not starting

Not enough information. What is the engine serial number? What is the injector part number that was removed and the new injector part number? Is there injection actuation pressure when cranking? Is engine speed displayed when cranking?

Cat 3412 E does not starting

I just overhauled cat 3412 E. I replaced new hydraulic pump and all unit injectors. What could be the problem. Do i need to reprogram the ECM?
