M&M Repair shop replace the fuel injectors and truck was still running no more
than 45MPH. Keep going forward and back which mechanic he couldn't figure out and
suggest. M&M advice me to take it to cumming and they dont want to deal with me when
it came to there fault. The injector where installed but still leaking the fuel inside. this
below from Cummings certified mechanic. We pulled the injectors out. During
disassembly we found damaged fuel connectors at the tip not making a good seal causing a
fuel leak. all connectors, injector fuel lines, and fuel rail are rusted internally. That been
found, there is additional parts that need to be replaced due to not meeting reuse
guidelines. During teardown we also found a failed EGR cooler. Causing excessive Soot
build up on Intake system. EGR cooler will also need to be replaced. We will need to clean
EGR system and intake manifold.
