How does a 2006 Cummins ISM work while driving?
hello I have a 2006 Cummins ISM (ESN, 35127420 ) This unit while driving surges with a small puff of black smoke, while watching the EGR data in insite, while at crusing speed arouns 1/2 to 3/4 throttle the EGR delta pressure bounces from about .5 to 4.5 inhg and the EGR cooler efficiency changed to NA.
Why is my Cummins ISX intermittent shut down issue?
That is a common problem with them leaking. They will only leak when they are running. After they shut off and the engine is running the main fuel pump will suck fuel past this pump. If the electric pumps leaks out fuel when it is on, then it will allow air to get sucked in once it shuts off. Thanks for all of the advice.
What to do if your Cummins engine is not running?

Why does my Cummins ISL run for 30 sec?
I unhooked the line at the tank and dropped it into a jug of diesel up front to make sure it wasnt the fuel pickup in the tank pulling the air since the fuel tank is 3/4 full. The little beads of fuel over the on the fuel lines in the basement area actually made me happy I was headed in the right direction.
Can a Cummins Engine update through the ECM?
If you do the update through the data link triangle connector in the engine harness by the Ecm , the chances of this happening are greatly reduced . Also loading the wiring like you stated with a bulb is good but it doesn’t tell if there are wires crossing inside the harness though .
