not rock crawler tech so flame on i just need help fast. 04 Duramax 2500HD 4x4 with 6.6 turbo and allision transmission. Problem Truck wont start shut off last night parked on hill. truck is not out of fuel gauge showed over 1/4 tank just to be sure put 5 gallons on and primed the fuel system, still wont start. Cycled plugs 5 times still wont start, cranks strong just wont hit. Truck only failed to start right up once before but cycled plugs again and it started right up does anyone have any idea at all? I cant really afford a costly dealer service

04? Isn't it under warranty still?

[jackedupjimmy]

had over 36.000 miles when i bought it, figured mileage didnt mean that much being a diesel

Probable has bad injectors if it has a lb7 motor gm extended the warranty to 120,000k i think. My .02$ :grinpimp:

Yeah if it's an LB7 the warranty is till 200,000 on the injectors and 100,000 on the motor. You should be covered.
