Sometimes after parking my car, you can smell the gas fumes. Its strong enough that if I leave it in the garage the fumes will seep into the whole house. The smell is stronger by the engine compartment, but you can get it in the cabin when the AC/Heat is on.

I don't see anything leaking, as far as I can tell. Besdies changing the fuel filter I cant think of anything else that it could be? The smell is driving me crazy at this point.

 

eww thats sic, you dont see anything leaking because gasoline evaporates really fast... maybe you can smell something leaking... o wait you already do... maybe it is possible to sniff out where the leak is... however, in a health point of view, this is not recommended... I dunno maybe have your fuel lines checked?

 

Its driving me crazy, I cant seem to pinpoint the smell. But my milage seems to really suck recently (150miles per tank).

Is there any common failure that anyone knows about?

 

Had a similar problem on my other car. It turned out the fumes coming out of the exhaust were creeping into the trunk and then into the cabin. I put weather stripping around the inside lining of the trunk and that was that. I dont know if you have a similar problem but I hope this helps.

 

I know that on the 3rd gens its the rubber hosing cracking and hose clamps getting old near the injector rails. Not sure about here though

 

I had that same probelem about 18 months ago, the smell and the bad mileage. It turns out my evaporator purge control solenoid was going bad. I had my mechanic change everything and it cost me $339 dollars. I would have someone check that first, there are several parts in that system that can fail. Have them at least diagnose it first before they start changing out parts. Also, what codes are you getting? good luck man

 

The only codes im getting is ignition inhibitor and knock sensor. Im changing both next week, but nothing engine related comes up.

 

are you running a straight pipe instead of a cat? I do on my boosted car and it smells like straight gasoline. Also a symptom of a charcole canister being full is the smell of gas. How about a leaking injector? Even if it is any of the things I listed you still should not get "that" bad of gas mileage.

 

on the leaky fuel injector.

 

Evap purge system
Leaking injector
Bad union on the fuel line
cracked fuel filter
split petrol tank

check it all out BEFORE your vehicle bursts into flames

 

check the hoses

 

I would add the fuel filler neck to the list as well, evey time I got out my car I smelled fuel, had it checked out I needed mine replaced. Got it here for $35 and a friend to install it for $30

 

leaky injector

 

Fuel lines seem fime, fuel filter I just had changed, tank is fine.

Whats the best way to test the evap purge control and injectors?

 

If the smell happens after you turn the engine OFF - I can almost guarantee it is the evap purge valve and / or cannister.
Had the same prob on my Gen 3 (Villager)
