i didn't think you had to remove the throttle body to change the rockers?

double check you reconnected all sensors, hoses & plugs, then post back.

Try and replace with old Rockers. If it starts maybe the valves are staying open and may need to replace Lifters because they aren't compressing enough..

You replaced the push rods? so they are the correct length for rockets that high a ratio?

Make sure your engine doesn't have overcasting where the pushrods sit. The pushrods might be touching the overcasting which in turn prevents them from working preventing car from starting. Crow cam do slim design pushrods which are recommended for ecotecs.

Also when i was manualy cranking the engine after fitting the 1.97 there was a pinging/tinging sound coming from the spring i think, but didnt do that after i installed the old rockers back in
