Ive recently installed heads, cam, intake, exahaust, throttle body, maf, etc. on a 2002 z28 m6. The car has a Texas Speed mail order tune. The car turns over great with great oil pressure however; it wont start. After several attempts I pulled a spark plug and its bone dry. Shouldnt I smell some fuel on there? I can hear my pump turn on with key and have great fuel pressure at the rail. I havent gotten around to checking for fire. When trouble shooting: with the key on should I be able to get 12v to my injectors and sensors. Can you check resistance on senors to see if they are in working condition? Any help is MUCH apreciated! Thanks!
