Does it have duel tanks? if so switching valve could be bad also it has two fuel pumps one primary and one secondary if the primary fuel pump is bad it would have ran sluggish and have lack of power it is not cheep the Main pump is $400.00 for a rebuilt and my guess it's the pump but check the fuel rail pressure and see what the pressure is that will give you an ideal

No power black smoke 2001 6.6 duramax


There are many reasons for black smoke. This color indicates incomplete combustion of the diesel fuel. Possible injector or injector timing problem would be the first thing to look at. Other causes can be a defective turbo... air restriction... engine running too cold... internal issues to name a few

2002 Duramax with high miles, 335k. Truck was running fine then on the way out of the driveway heard a loud "pop", engine lost power but continued to run. Now, I hear a turbo whine I didnt hear before when...


Start at the turbo and check for loose or blown air lines . Check the intercooler for cracks. The turbo whine is normal but you would not be hearing it as the turbo is controlled to vary the amount of boost needed for the throttle setting. If you have to use starting fluid to start a diesel then it is time to consider a re-ring and bearings for the engine.

2002 duramax will heat up underload but not at idle any ideas why


No diesel I have ever owned will heat up to operating temp while idling. I have had semi's and dump truck and a Dodge with a Cummings turbo diesel. If you don't idle a diesel up to around 1200 rpm while sitting the combustion chamber temperature will drop because the diesel does not ignite fully at low rpm. You may also notice after an extended period of idling 1/2 hour or more that when you pull away the exhaust will be whitish blue because of the unburnt diesel fuel sitting on top of the rings. Also extended low idle will wash down the cylinder walls with unburnt diesel and remove the oil from lubricating the cylinders and rings. Hope this helps you understand why your diesel won't heat up while idling. Mike
