I'm trying to get this right so here are the questions, warm engine up for 5 minutes, remove fuel pump fuse and fuel injector fuse ,crank truck until it runs out of fuel and turns off. Remove all spark plugs and since po302 code is the only misfire start with it and hope it's over 100psi .

- Transmission Woes :-(
  
  By davester · Posted 2 hours ago
  
  ouch to both. $650 for hooking up their computer and hitting a "reset adapts" button is ridiculous. and I would want to know why they think a new transmission is required besides the manager wanting a bigger bonus this quarter.
- Oil Consumption

  Thanks everyone for your input on this subject. It was very entertaining but not educational. Bottom line. The GM 6.6L should not consume oil, which it does, no matter the driving style. Only time will tell if it lasts past 100k. I am hoping 200k+. GM needs to get back to the piston rings and top fuel injection which works and has been proven. You may now move about the cabin.
- Denali Grille question

  So for anyone else looking into this, yes the surround fascia is separate and easily swapped. Yes i went with the denali vader chrome. Will see what happens, truck isnt on highway much and gets cleaned often. Seem as rock chips and bugs have a helping hand with the problem.
