If the problem is with a lawn mower or small engine: There is more fuel than can be ignited by the spark plug. Possible culprits: bad spark plug or wire; clogged air filter; carburetor float stuck open; carburetor choke baffle stuck closed; carburetor settings need adjustment for leaner mixture. If the problem is your vehicle: There are too many variables including sensors, pumps, regulators, etc. It would be best to take it to a qualified mechanic.
Depends on the type of flooding. Hopefully the gas flooded and not the water flooded. If it's flooded by gas try starting it with throttle wide open. If it doesn't work after a while, remove spark plugs and crank engine over for few seconds (remember to watch out for the spark) Install new spark plugs. If the engine is flooded from water, you will have to remove the spark plugs and crank on it for a while till all water comes out. *I have personal experience here* Install spark plugs and attempt to start, if not remove plugs and keep cranking. It may fire for a second or two. Keep removing spark plugs to dry them off and crank some more. Keep this up back and forth for a while, or till engine fires up.
Flooded in the river or flooded by gas? Any "check engine lights"? Full gas pedal depression is the normal way to clear gas flooding or first remove the spark plugs and blow out the excess gas.
Removing the spark plugs and finding the spark plugs soaked with gasoline. Also the engine oil may have a strong odor of gasoline.
Sounds like you flooded it. Pop the plugs out and let the gas evaporate and try it again.
If you mean flooded with gas, then remove the spark plugs, crank the engine over for a couple of seconds, and install new plugs. If some time has passed, then the fuel will evaporate, just the plugs will stay a little wet. So, the new plugs will do the trick. If a lot of gas has passed, then it would be a good idea to change the oil and filter. Gas will pass thru the rings and settle in the engine oil, and if it was that bad, then a little shot of transmission oil in the spark plug holes and crank the engine a couple of seconds will help the rings settle. Then install the new plugs.
why do my spark plugs smell like gas but the conductor is dry just the threads smell like gas and are also wet
yes - 8 spark plugs for a gas V8 engine
Change your spark plugs!!
yes
Every gas burning internal combustion engine has spark plugs. Diesel engines do not. Your Impala is not a diesel, so it has plugs.
No, Diesels don not need a spark plug.
It could be the engine or maybe water could have flooded the spark-plugs.
