i just bought a 97 2 door blazer and while its running and for a short time after i shut it off i get a strong fuel oder in the cab and from outside on the driver side of the car any ideas on what it could be because i cant find any fuel leaks any where

 

Find the test port on the fuel lines and see if the shrader valve is dripping gas. Happened on my 95 2X's. Same symptoms easy fix.
