Feul smell in car when cold out

First check for fuel leaks. Be safe. Next I would pull the spark plugs and smell them for gas. If you smell gas on them, they are fouled out. Start with replacing them. Also check for spark. These are the two basics to check first. Spark and fuel. You have fuel because you can smell it.

Its a hot start issue.

Can be related to low fuel pressure or problem with crank sensor.

Also it can be weak battery or starter.

But possibilities are to be inspected to confirm what exactly it is.------

To troubleshoot and confirm the issue,i suggest you refer few solved help links with similar types of problem like yours:------

===========

These details will help.

Thanks.

should a tenant have to tolerate a putrid odour from an outside vent caused by natural gas?

That isn't much to go by

Strong smell where?

Do you have a check light on dash &
codes for EVAP System or a fuel
leak somewhere?

All we can do is guess

You can examine your vehicle & find the problem

There could be a few reasons for that happening....It is most likely a FEUL problem. Is it feul injection or carburettor?? If it is a carburretor, then there could be dirt in the jets. You could also have an inline filter that is blocked & not enough feul is getting through to the carb. Another thing that could be causing the car not to start after being running awhile is if the feul line is too close to the engine and is getting too much heat, causing the feul to "bubble" and faporise in the line, untill it cools down. Another cause could be that the float level in the carb is set too low or you have a faulty needle & seat.

Hope this helps.

sounds like you have a leaky gas line,...the fuel pump is in the gas tank, so when you turn the key on, the pump is activated and pressurizes the line,..... good to get it checked out on a lift,....good luck, cracklin joe

Freon gas has no odor. You might be smelling an oil or lubricant odor possibly. Hopefully not GASOLINE. Hope this helps.

get your feul filter checked ... I had the same problem then when took it to mechanic he showed me the condition of feul filter was real bad.. get it check plz

get a couple bottles of gas line antifreeze .. if you don't already use it and add it to the gas.

P.S. in minus 40 i don't even get out of bed... minus 23 here last nite... isn't winter grand

Remove the vacuum hose from the fuel pressure regulator and have some one turn the key on if it leaks gas out its bad this will explain the smell. Also does it have a hard time starting when it sits for awhile ?
