67al Oct 6th, 09, 8:27 PM Trying to help a friend, Truck goes into limp mode and trouble code says # 2 cylinder fuel circuit problem. Used the Auto Zone scanner to reset system and truck runs fine for a day or two, but starts that limp mode stuff again. Any ideas?

At least 100k anyway, that is the normal DUramax warranty. Either way ..... get it to the dealer and get it fixed, if it is the injector issue it can cause a major engine failure.

Daren Bowtie-72 Oct 8th, 09, 5:45 PM Injector issues are pretty common with the duramax. The injectors, pipes, and sometimes even the FICM (fuel inj control mod) could be to blame. | ||
