i put a complete a6 head with stock cam gear on my b7 block and the car is timed , getting fuel and spark but is not starting before i had a adjustable cam gear on it and set the time and advance it all the way and the car almost started.

 

does the car have compression did you change the headstuds and headgasket??

do a compression check..

 

are you making sure your number 1 piston is TDC when you check your timing?

 

yeah i did all that messed with the timing alot and still wont start. i got it to flash a code and it was the tdc sensor will that make a car not start
