Hard Starting issue 05mcs

Having a hard start issue with my mini. It starts fine when the motor completly cools off. But if you drive it and shut it off and try to start it back up in 10 min or so it turns over alot longer than normal and smells like gas. If you shut it off and start it back up right away it starts fine even when its warm. Was thinking it was the Engine temp sensor after doing some research. Spark plugs where just changed, injectors, and added msd coil with new wires. This issue was there before all of this was added and now it seems to be getting worse. There is also no codes or faults when checking with scan tool.

Any Ideas on what is causing this?

Thanks,

Ty
