cause may be the coolant temperature sensor, it's signal is used by the computer to meter fuel to the injectors when the coolant sensor goes bad the car will be slow to start the first time and there will be a strong odor of gasoline , turn it off and it starts right up
No service engine light? A loose gas cap will set a light.
You may want to inspect your fuel filler neck and anything close. For a long while its not uncommon for a person to report the fuel odor issue and have it be where some low life cut a filler neck or puntured a tank to steal fuel. But if that were the case there would usually be a service engine or gas cap light as the systems now days monitor pressures so they can detect leaks in the Evap system.
When you mention a smell though under the hood, do you think the smell could be exhaust? I have seen those manifolds crack. or maybe just a leak from a gasket or exhaust donut.
tu bomba no esta con la presion correcta cambiala y el sedaso y filtro de gasolina por eso se apaga y falla comprale una bomba bosh de gasoline no aditive to tank las inpuresas te danan los inyectores la bomba le queda la de astro yukon s10 truck
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.
do u have a check engine light on? do u overfill the tank? which is to say when the filler nozzle clicks off do u still try to put more fuel in? in any event u most likely have a overloaded carbon canister, pull the canister out and check it for gasoline saturation, the carbon canister is located under the car in a tray near the fuel tank.
for sure there is fuel leafing but you have to locate from where, usualy this can happen from a leaking fuel pressure regulator and this can drip on the hot manifold and cause it to boil and smell the whole car secondly the vapor canister could be damaged and cause the same problem
