Water Petrol Something Comes Out from Exhaust Vol 167 Cranks when turing on smells like gas coming out of the exhaust 1998 2002... http://www.automotiveforums.com/t1076465-gas_coming_out_of_exhaust.html
At start up? or all the time? At start up is an internal fuel system problem. All the time is the fuel (system) is leaking out. If you smell it while driving, it is close to the engine. Find it , fix it now. I had a fuel line bust open, It was on fire before I could pull over. Killed it, pulled over and watched it burn. Seen it happen to others also.
