Why does my Duramax DMAX throttle response not work?
Why does my Duramax DMAX throttle response not work?
When it is cold outside, the Dmax isn’t much of a performer until it gets up to operating temps (which could take 10 miles or so). If the fuel filter has never been changed, then it is likely due to be done.
Can a Duramax engine run in the Cold?
The only question I can’t answer is how the new smaller duramax engine does specifically in the cold. I could always Start my 2015 Ram with a Cummins without plugging it in until -22F but after that it got cranky and didn’t run great so I would plug it in after that.
What’s the normal temp for a Duramax Diesel?
It’s not normal. Temps drop to -40 F here and I have never had a problem with the way my diesels run. These diesel motors are not the dinasaurs of the 80’s. That is still a big misconseption. Like Shaners said, change the fuel filter. Also check your air cleaner.
Why is my DMAX not working on my Silverado?
On the road the RPM’s are right where you need them, so a little throttle just sets you back in your seat with no downshifting. When it is cold outside, the Dmax isn’t much of a performer until it gets up to operating temps (which could take 10 miles or so).

How can I Keep my Duramax Diesel pump healthy?
However, there are measures you can take to keep the pump happy and healthy, the first being to always buy your diesel from a high-traffic, reputable filling station that’s known to dispense good, clean fuel. Second, always change the fuel filter at or before the recommended service interval.
What happens if the crankshaft on a Duramax goes bad?
Perhaps the most devastating of all Duramax failures is a broken factory crankshaft. Not only does this mean game-over for the engine, but it results in a truck that’s down for weeks (if not months) and a huge chunk of change missing from your wallet.
What kind of pump does a Duramax cp4.2 use?
Like all Duramax engines from ’01-’10, the LML was also void of a lift pump from the factory. This means that not only does the CP4.2 have to pressurize fuel as high as 29,000 psi before sending it to the rails, but it also has to pull its low pressure fuel from the tank.
