This weekend I Installed new cam, Trick Flow heads, 1.6 roller rockers, timing chain, 30# injectors, intake, throttle body, DBX 97 mass air ( the program has been downloaded to mass air)....now the car won't start......everything turns over fine....have good spark.......I have not installed the new fuel pump yet.....Is it possible that I have it 180 degrees out of time? If you are cranking it over you can hear what sounds like it trying to fire but out the exhaust....... If it is out of time what is the best way to fix it? When I installed the timing chain I made sure #1 cylinder was at TDC and marks were lined up on the sprockets.....
