Flush would have been good back then but now i wouldnt trust the injectors & the pump may need re calibrating
check for leaks & or cracks at joins in fuel lines

The Duramax fuel filter assembly is bad about sucking air. Replace the fuel filter assembly. It comes with a new fuel filter.
I need some good feedback.

02 Duramax deisel mixing deisel fuel into engine oil


'02 Duramax engine has the injectors under the valve covers. There is a set of "fuel return" lines that are attached to the injectors under the valve covers too. This is where I would be looking for fuel.

Car stopped running after about a mile of getting gas, didn't start back up. Auto mechanics say the gas looks yellow with a blue tint to it


You may have mistakingly put in deisel fuel.If this is the case then the tank needs to be drained and replaced with gas.It will start hard and then smoke some but it not hurt the engine unless it has gotten down in your oil pan.Be sure to pull the oil dipstick and check to see if it is over full before starting.If it is change the oil and the oil filter.[Hope i'm wrong]

How do I change the fuel filter on a 2002 gmc sierra duramax deisel? And where is it located?


becarfull, the fuel filter os on the passenger side of the engine compartment. after replacing the fuel filter you need to prime the system to get all the air out of the fuel system otherwise the engine will crank and crank and never start. if this happens, you'll need how to prime the system or tow the truck to the nearest Gm dealership.
read the owners manual for help.

No start on duramax at time when hot


IF THIS IS AN 2007 YEAR THE FUEL PUMP SHOULD BE IN THE TANK. IF THIS IS A DEISEL THE PUMP COULD BE ON THE FRAME RAIL BUT ONLY HAS ONE PUMP THE PUMP RUNS BOTH TANKS.
CHECK FOR ANY CRACKS IN THE FUEL LINE ALSO. BUT IT SOUNDS LIKE THE FUEL DRAINS BACK INTO THE TANK WHEN IT SETS THIS IS A SIGN THAT THE FUEL PUMP IS NOT HOLDING IT'S PRIME AND THIS NEEDS TO BE REPLACED

Got some gas at Kroger,engin off;; had driven less than 5 miles made one stop,engin off;; a mile later loss power,check engin lite on, it started after a minute;; two miles on did it again;; got to store...


Remove the fuel filter and empty it into a glass jar...If you see any water at the bottom, likely there is far more in the tank (there is at least a gallon or more below the fuel pickup) If there's water in there tank needs to be drained and cleaned.
