Need info on 06 gmc sierra

GMC utes seem to be a REAL problem should have bought a Ford or Dodge.
Do not belive the OLD story--- If you can not afford a Ford dodge a Dodge

I am assuming you have a manual transmission. First I would check to see if it came with the dual flywheel. If it did then this is the problem. If it didn't then the pressure plate is weak or the clutch is worn out. If it is an automatic, there are several things that would cause this. Torque converter. solenoids, clutch bands, clutch .....

the headlight housing is held in by 2 L shaped pins that rotate outward and pull up and out, then it can be pulled out.

7 for the crankcase and one for the filter. this info is in the manual.

just for the engine about $4000

fuel filter is is in the center of engine at the back by firewall round canister type with screw top. unscrew replace, fill with fuel. 40 -50 $

Problem with Diesel Fuel System. Gmc 2002 duramax 2500 HD 4x4 will start 

maybe the clutch forke not in the right place

sure if you have all the computers and wire harnes.
