1991 Toyota pick up gas odor

My '91 pickup has just developed a strong gas odor. It is only noticable when the truck has been run for a while, and then it is very strong, both inside the cab and outside the vehicle. If the truck sits for a while, the odor goes away. I have looked in the engine compartment, but cannot see anything obvious, and frankly I don't know if I am looking in the right places.

    I have a simular problem with my 1991 3.0 litter toyota pickup.It has a strong smell in the engine compartment and in the cab. No visable signs of leakage,even pulled the plheneum off and found no signs of wetness.I also put a gas sniffer tool around all the injectors and fuel rails and still nothing.Took off the canister and found it to be dry.Still been driving it and if I turn it off and let it sit for a while it will not start unless I press on the gas pedal. NOT sure if it is bleeding back and this problem is associated with the smell problem.Thanks for any suggestions!

I have a 2005 chevy malibu maxx v6. car runs great, no hesitation or stalling, however a intensly strong odor of gasoline suddenly began about 3 wks ago, and is gettin stronger by the day! it Can be...

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.

Have 1999 s-10 2.2 liter. has gas in the oil, gas coming out the tail pipe, shakes badly, and has very strong fuel odor.

Might be a frozen (stuck) piston ring, or bad exhaust valve. To narrow the problem, perform a compression test. If you will have low compression in one or more cylinders let me know. I will help you to find if it is a ring or valve.

Strong gas smell and poor gas mileage

If the gas odor is coming from the engine, than the problem is most likely a cracked or poorly seated fuel injector.

2005 Chevy Impala exhaust smell

neither one of these would cause gas to leak. sure it is not coolant ? if you think it is gas it is not safe to drive car as it could catch on fire. possible cause would be a leaking injector.
