Removed fuel rail to replace intake manifold. Replace everything and now it will not start. I did not have the fuel rail secure and was loose.... now I can not get car to fire... will turn over fine and fuel pump is fine.. I am guessing that I did not have proper fuel pressue and computer prevented it from starting.... ?? Help please.

I would go through the entire reassembly process again and make sure everything was put back together correctly.

 

Stupid question, but did you reconnect the wires to the fuel injectors?
