Won't start after reinstall intake manifold

[cosmaa1]

I have a 2012 A4 B8.  I had a loose intake manifold bolt that would not tighten. I removed the intake manifold and installed the heli coil. Now the car will not start. Just turns over and a gas smell. The car ran great before I removed the manifold. I don’t think I forgot any connectors. Any suggestions? If somehow there is a connector problem, can someone identify which one to check that may cause this issue. Thanks TC

I'd recommend a diagnostic check to see if any fault codes flag up

Have a good look around the intake manifold to check if you have trapped a wire maybe the wires for the crank or cam sensor or something else that could be shorted to ground
