How is the engine running, is it rough, misfiring? Has the PCM identified a circuit failure, or a misfiring cylinder? [links]

If you have an injector that is either stuck open mechanically, or being commanded open by a grounded wire between it and the PCM, or a failed driver (transistor) in the PCM then you could end up with raw fuel dripping from the exhaust. Another possible source of that much fuel would be the fuel pressure regulator leaking and the fuel traveling into the intake manifold via it's vacuum hose. here

If you are certain that this is fuel and not condensation from exhaust gasses, you really should see a shop. The potential for trouble beyond the injector issue is significant. You could trap fuel on top of a piston and hydro-lock a cylinder. You certainly are diluting the oil which could cause wear inside the engine, and of course there is the risk of managing to ignite the fuel at the exhaust opening. [links]

1.pull the spark plug.
2. Drain the gas tank.
3. Make sure the switch is on 'off'.
3.5 hold the throttle wide open.
4. Pull the starter a bunch of times.
5. flip the saw upside down and pull it a few more times(make sure that you do this where no dirt will get into your engine).
6. Take a break. [links]

If you can figure out how to put the piston at TDC you can do steps 1 through 2 and then just let the saw sit in the sun while you do something else. Just don't be in such a rush. If your life depends on getting the job done always have a spare saw.

When using a gas cooktop in a kitchen, is it okay to recirculate the air with an exhaust fan or must the fan be vented outside?

I have a Craftsman lawn tractor with 17 HP OHV model # 311707-0132-E3. It stopped running & now when I try to start it, it won't. It will crank a couple of times, but then won't even do that. On closer inspection a see gas dripping out of the front especially when I tried to start it. It looks like. [links]

Part 1-My 2002 home's gas exhaust came apart and was spilling gas in the house. I wasn't able to go in the garage it was so bad. What is the code on securing the elbows/exhaust? more

Hello, I have a gas stove located on an interior wall. Is it a safe practice to run the ducting from the interior wall, down into the basement (4 foot), and turn 90 degrees to duct outside (8 foot)? My thought is to mount the motor/fan in the basement at the exterior wall location. Do you.

I'm sure there's something I missed, but this is everything I can think of off the top of my head.

Alright, the car runs well enough after a bit, so timing doesn't seem like it'd be the issue. Fuel/air mix is determined by preset values in the ECU's memory, so that's probably out. If it smells like gas, then you're definitely getting fuel. HMMM. [links]

Fortunately, your car is dated post 1996, making it an OBD-II car. Phillip's suggestions are all very good, though personally, I would start by trying to pull an engine code. If you're smelling gas, then your emissions system is definitely on the fritz and probably knows it. This causes the computer to "throw a code" which SHOULD make your Check Engine light turn on. Go to your local auto parts store and ask them if they can pull the diagnostic code for you. A lot of shops will. Or, if you're feeling wealthy, a full-featured code reader can be purchased for around $150. (A mandatory puchase for any SERIOUS automotive DIYer) There are cheaper ones, but a lot of them only work for certain makes/models and don't provide descriptions for the codes, forcing you to look them up elsewhere. Personally, I am of the "buy once, cry once" mentality. more

David, what make, model and year is your car? Standard or automatic? How many miles? When was the last tune up? Any service engine lights on? How long has this been going on? Need more information to try to assist you. Thanks.

You say the car was serviced, what was this service? Is this a reputable shop? If they tried to sell you an engine claiming that your engine won't get far (and yours did) I might question their "service" (sorry I'm a mechanic cynic). Anyways. To run, an engine needs a few basic things: fuel, spark, air, compression. Lack of any of these things can cause troubles. The smell of gas indicates a couple things. 1 you're definitely getting gas and 2, combustion is not occurring completely. Incomplete combustion suggests (to me) lack of spark or compression (incorrect air/fuel ratio is possible but we'll try that later). If you can, pull your spark plugs and check their condition. If you can go to a local auto store and rent a compression gauge and measure your compression that would be great too! Let us know what you're able to find :)

Oh WOW. So THAT's what you meant by cranking! That makes WAY more sense. Double thumbs up for the youtube vid. That was a stroke of genius. more
