Is the Duramax diesel engine like a gasoline engine?

The Duramax is not like a gasoline engine. There is a low and high side fuel system. The high side runs at 6000-26,000psi, so no your Snap On tester wont test it. The low side actually runs under vacuum as the injection pump sucks the fuel from the tank.

Why is my Duramax diesel engine not working?

The trucks computer keeps track of how much fuel needs to be added or subtracted from each individual cylinder to make the engine run smoothly, and this value is called the balance rate. If one cylinder is contributing too much or not as much as the rest, the cause is usually a bad injector and the cure is a replacement.

How big is the gas tank on a Duramax?

How much power does a Duramax Diesel have?

Power was at an all-time high coming in at 397hp and 765 pounds of torque, and in order to provide this much power while still keeping pollutants low, GM needed to be able to increase the pressure in the fuel system to levels above what the tried-and-true CP3 could safely deliver.
