Black smoke tomach fuel eting - 1988 Toyota Cressida

Yes

Black smoke is fuel. One or more of the fuel injectors could be stuck open and when you shut it off, the fuel drips into the cylinder. When you start it, that extra fuel burns and blows out black smoke. Blue smoke is oil and white smoke is antifreeze/water.

Smokes can be of three colors.
1. White smoke.
Excessive white smoke reveals presence of water in fuel, thermostat valve stuck open, or burnt cylinder head gasket.
2. Black smoke.
Black smoke could be observed due to the unburnt fuel or higher percentage of Hydrocarbons during the combustion process, defective regulating valve, ruptured PCV valve, low fuel pump pressure, defective charcoal canister, ruptured or leaking fuel injectors.
3. Blue smoke.
Blue smoke reveals the engine failure.

Hi there:Black smoke is caused by excess fuel that has entered the cylinder area and cannot be burned completely. Another term for excess fuel is "running rich." Poor fuel mileage is also a common complaint when black smoke comes out of the tailpipe. Black smoke out the tailpipe is the least cause for alarm. Excess fuel will usually effect engine performance, reduce fuel economy, and produce a fuel odor.
How did the fuel get into the cylinder in the first place? Some of the causes of excess fuel are a carburetor that is out of adjustment, a faulty fuel pump, a leaky fuel injector, or a faulty engine computer or computer sensor. If black smoke is present, check the engine oil as in the white smoke example to make sure excess fuel has not contaminated it. Do not start the engine if a heavy, raw fuel smell can be detected in the engine oil. Call your mechanic and advise him of what you have found.
Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

black smoke is the vehicle is running rich, to much fuel. excess fuel enters the cylinder and does not burn completely. poor fuel milage is also a common complaint when black smoke comes out tailpipe. ( its running rich ). have a good day !

Black smoke indicates no air, check your air filter, if you have done that and it is ok, check the PCV valve. Thats about all that I can suggest. Hope that helps.

Black smoke is burning oil. Blue smoke is usually transmission fluid due to a leaking modulator valve in the older auto transmission. White smoke is due to water getting in to a cylinder from a bad gasket, cracked block or a cracked head. Black smoke from engines on starting and/or running tends to mean there is fuel leaking into the engine, or the fuel mix is incorrect and not atomised correctly. the main causes are normally a nakered air filter that isnt letting enough clean air into the engine to mix. a blocked fuel filter, which is either not letting enough fuel in, or in some cases, a faulty fuel filter which is letting too much fuel into the engine, and causing black smoke due to excess burning. Black smoke is a fuel/air mixture suggestion problems with injection or carbonation. Cause of black smoke is due to running rich in the fuel air mix. Check the oil,the oil leak,the air filter,the fuel pump and fuel filter to confirm the fault.

Thanks. Keep updated for any more query. You can rate this solution and show your appreciation

black smoke is from engine oil loss through the head cylinder or piston rings

Black smoke is excessive burnt fuel. White is excessive unburnt fuel. Have your turbo checked and the air filter. Good Luck
