When I start my car for the first time in the day it start right up. When turn it off for 15mins it won't start on the first crank the CEL is on I pulled the code its P0401.

P0401 is ECR Insufficient Flow.

Do a search on P0401, or EGR Valve or something related.

I think you will fine the EGR valve needs to be cleaned or replaced.
