Strong smell of gas..no visible leak...Any input??


All it takes is to have fuel seep for a smell. Inspect all fuel lines and fuel injectors/pressure regulator for dampness/stains. Make sure fuel cap seals well. If fuel tank is filled to the max, it can cause the charcoal canister to fill with fuel as well resulting in a gas smell.

Why is my gascap light on?


The "gascap" warning tells you that there is a leak somewhere in the fuel tank, fill neck, or gas cap that is preventing vacuum from developing in the tank. If you are certain that your gas cap is good, the second most likely culprit is the fuel fill neck gasket was compromised during the accident, or that there was unnoticed damage to the gas tank which is not allowing a vacuum to develop inside the tank.

GASCAP and engine light


A bad gas cap will cause the light to come on, of so replace the cap. The vent is not working if gas is coming back at you. Replace with new.

Dodge dakota 2005 -check engine light(gas cap)gas cap was replaced.Fuel spills out when filling tank.Fuel lines were smoked and no clog was found.


There is a check valve in the filler hose to stop fuel from coming out seems yours might be stuck , run a metal coat hangers inside the filler neck while prying open the little fill flap. see if that helps OR you are not or have no VENT to AIR in your evap system causing excessive tank pressure.

Gas smell inside car and when refueling it constantly stops like the tank were full


beetles have what they call a "positive pressure"gas tank(the vent is in the cap)and it has a restriction in the filler to stop fuel leaking out if the car overturns.So if you try to put too much fuel in it will kickback and fill the recess in the fender.hence smell in car after refilling.......
(had 30 plus beetles in 3 years all great....when i worked for vw).

My Mazda MPV randomly begins to "chug" and act like it will die at a stop. the check engine light comes on. Started about 6 months ago. Seems to happen more when it rains. If I tighten the gas cap it stops...


the gas cap and check engine light thing are related in terms of the EVAP system, or the evaporative emisions system. This is NOT where your surge, or "chug" is coming from. The surge could be coming from a Exhaust Gas Recurculation valve that is starting to bind or "hang up" a bit. DO you notice this happens more at lights, or when coming to a stop? if so it could be an idle air control vavle.

Check engine light code 442 reolaced gas cap still coming back on after clearing


Then either it's the wrong fuel cap, or you have a leak else where. I'd look under the back at the fuel tank where the fill hose goes to the tank. The tanks like to break there. Most of the time people smell the gas before the light is set, but it may be differant in your case.

Sounds like water/debris in the gas tank. Try adding dry gas to the tank. Changing the fuel filter also a good idea.
