Your 1993 911 has electronic fuel injection. When the engine is cold, it automatically richens the fuel mixture. This is the equivalent of closing the choke on an old car or tractor with a carburetor. When the car is going down hill, the car is not burning this excess fuel. You are smelling it coming from the exhaust. Once the car warms up, the engine computer automatically leans out the fuel mixture, essentially turning off the choke. Now you don't smell the fuel.

I have a 2006 PT Cruiser, Touring non-turbo model, which does not have a schrader valve or a fuel pump fuse or relay. How do I depressurize the fuel line to remove the injector rail?


If you don't know the source of the gasoline smell, why would you go to the trouble of replacing the O rings? It would be better to identify the source before jumping into a repair like that only to find out after all that work, it still smells like fuel . you can loosen the fuel line fitting slightly to release pressure. I'd do that on a completely cold engine.

My 2009 xf has just 34000 miles. Last week I start the engine and I could smell gas in the car for about 5 minutes. I waited until the smell was over to drive. From that day, every other day I was sme


Was this the smell of burnt fuel or raw gasoline? If this started after it began getting cold outside this can indicate a problem with the EVAP system in the car. This may or may not cause a check engine light.

This site reported a 2010 model of your car having this same symptom.
They found the injector seals to be leaking.

That can be a very serious issue with the potential to cause a fire. I would have it checked by a professional mechanic and specify your concern on the injector seals being checked.

When driving i can smell gas in my 2000 lexus es300


possibly your O rings which isolates fuel injectors from engine block are getting old and letting gasoline go out. it is very dangerous since it can cause fire. do not drive.

another cause is broken loose or cracked fuel lines. this is equally dangerous since it is under hood close to hot exhaust manifold.

if smell is from exhaust manifold, which means not the smeel of gasoline but exhaust fumes, this can be caused by broken exhaust manifold or a crack on it or problematic exhaust manifold gasket.

I changed the oil in my 2001 Impala 3.8 and noticed the oil had a gasoline smell.


Some smell is normal if it has been quite sometime between oil changes. This happens more with short distance driving.

How does it get there?

Through cylinder blow by when the engine is cold. The piston rings leak minuscule amounts into the oil which add up over time.

If you are having no other running issues (IE black/drk grey smoke out tail pipe with oil residue on pipe tip) I would not be alarmed by this.

91 Maxima Gasoline odor when I first start the car


If it is running fine, the busted bolt isn't the source of the gasoline smell. The intake manifold has vacuum, so the smell wouldn't be getting out, air would be going in, and a vacuum leak would give you poor idling. The exhaust manifold wouldn't have much raw gasoline smell. But it would have loud noise if the broken bolt were causing an exhaust leak.

Check that the vapor recovery line is not broken or disconnected. The hose connectors get cracked. If that were broken, it would cause a gasoline smell after the car has been sitting, especially if it has been sitting in the sun, heat driving gasoline vapor out of the tank. It is supposed to condense in the vapor canister, but some escapes if the line is broken. If it is broken, driving would **** out the gasoline from the line and the wind would dissipate the smell.

Or it could be a leaking injector. With the injector cover off, engine idling and cool, you can visually look for raw gas around the injectors and injector rail connections.

Hope this helps.
