Ok guys some of you know my dad has an 04 avalanche with 6" lift 315/70/17 falkens on methods. Well he had a diablo chip in it, took it to the dealership for work, got it back, noticed it was horribly sluggish so went to put diablo back in truck realizing it was no longer installed and now the truck wont even turn over. All the regular electrical stuff works, power windows, locks, etc... But when we turn the key to start it, NOTHING!
Any one know what it is?!?!
