Question about Cars & Trucks

1 Answer

I smell gas occasionally. Doesn't seem to be any leaks anywhere. the check engine light comes on occasionally, then goes off.

I purchased the car. Didn't smell any gas during test drive. Drove it home and started to get a slight gas odor. When I shut off motor and lift hood there is no odor. I'm thinking this could be a sensor going bad. But not sure.

SOURCE: car I was going to buy smokes a little

The only way the brakes would be 'smoking' would be if you were beating the @#Q$$ out of them, like racing through corners and hitting them hard for some time. The smoke wouldn't be coming from the rear of the engine, it would be at the wheels. If the fuel pump was bad, the car wouldn't run at all. So my advice to you is to run away from this car as fast as you can, and don't look back, no matter how much you like this car. If you buy it, you'll be spending a lot of $ to fix things. The owner is not telling you the truth about 2 things wrong with it, how many other things is he hiding? Good Luck! Curt

SOURCE: Yesterday I purchased a 97

If your test drive was short, but your drive home is longer, it could be a coolant leak. Coolant creates a thick white smoke when it burns. If it's coming out of the tailpipe, then it must be coming through the engine at some point, possibly from a failing head gasket.

A fairly inexpensive test for this is to drain and flush the radiator, refilling it with water, running the engine to warm it up, then drain and flush again, refilling it with water. Be sure to drain and flush the overflow reservoir as well if you can. And please be careful working with a hot radiator - steam burns skin very easily. This should remove at least 75% of the ethyl glycol antifreeze that causes the smoke.

Now, when you run the car up to temperature, if it still smokes white, but much, much less, then it is in fact coolant leaking into the engine and being vaporized and pushed out through the exhaust. The most likely point of failure is the head gasket - which means a several hundred dollar fix.

Sounds like there is a blown piston, to be sure have a compression test done on that #2 cylinder, if the reading is low, then you'll know.
A friend of mine had a 95 that did simular things only a little more,
it started smoking, dash lights flickered, etc. Finally, he had to get rid of it, the piston rod went through the engine block.

I smell gas but i'm not lossing any.


My first question is - is the check engine light on when you are driving ?
You could have a leaking injector which could be causing fuel to escape thru the exhaust. You could also have a leak in the vent system for the gas tank.
The need for coolant and oil if no leaks are visible usually means the engine is burning the fluids because of an internal engine leak or head gasket problem.

More than likely, you have a failed fan clutch. That is a frequent problem on the 4.3 I6 engine. It will cause a roaring noise and "vibration" and allow the engine to overheat at low road speeds. As far as your check engine light and other driveablity problems, it may or may not be associated. Have someone with a code reader check it. The TrailBlazers were infamous for electrical gremlins.

Gas leaks are serious. If it was in the evap system the engine light would be on. So you need to check or have checked the entire system. From the top of the fuel tank, the lines under the vehicle up to the engine(mostly steel) At the engine they turn to rubber or hard plastic. Also check the fuekl rail and injectors. There are two Orings per injector. And check the fuel regulator. I lost my van to a gas leak that ignited from a faulty spark plug wire.

SOUNDS LIKE THE FUEL PRESSURE REGULATOR IS SLIGHTLY LEAKING. PULL THE VACUUM HOSE OFF AND SMELL THE OPENING FOR GAS SMELL. CHANGE AS SOON AS POSSIBLE.CHECK ENGINE LIGHT MAY BE ON BECAUSE OF O2 SENSOR BEING FLOODED.OTHERWISE, COULD BE A VACUUM LEAK.

check the fuel line hose near the fuel regulator for wear as they tend to leak or corrode causing a gas smell inside the car. My 2000 Kia Sportage just had the same problem with the gas smell inside the car.

99 dodge dakota has gas smell in cab when heater or ac is on


sounds like you need to look through the engine bay and see if your fuel lines are wet anywhere!! There might be a possibilty that you have a leak around the gas tank so jus crawl under the trunk and look to see if it has any kind of wetness around the tank or hoses coming out of the tank!!
