i hope this is the right place to post this. I love my trailblazer, and its breaking my f***ing heart. I recently had the driver side steering knuckle, lower control arm, and tie rod replaced and aligment fixed. I was excited cause now i could get it inspected. Problems arise from here. Got the oil changed, and failed the inspection. Top brake light works, but not back side brake lamps. Got home, pulled the fuse and its good. Went to start my 03 trailblazer ls 4.6 il 4x4 and now got a reduced engine power light and wont start. Wtf happened to my girl? It was running perfect till after i got back home. Any responses will be greatly appreciated. Had a mobile mechanic come by, and he "thinks" its the fuel pump. But was not positive.
