Truck starts but stops immediately and smoke comin out of my tailpipe


Well it depends on the color of smoke if it's WHITE; it could be a blown head gasket (check coolant levels and then oil to see if it is milky looking) BLUE: could be burning oil, which could result to fouling plugs (check spark plugs for fouling) BLACK; too much fuel flooded (check spark plugs for fouling)

I ran my chev. 1990 pickup out of oil and now it smokes so bad. and i think my fuel pump is going out but not sure??


Sounds like you may have ruined the piston rings and this is allowing oil to seep in to the combustion chamber hence your smoke. Or if it overheated when you ran out of oil it is possible that you have a bad head gasket now. Check both your coolant and oil for signs, oil will have a white froth, or darkening of your coolant. Hope that helps you.

1999 saturn sw has blue smoke coming from tailpipe. I would like to know if it has anything to do with head gasket


blue smoke is usually oil burning- is it light or heavy- if light- change oil and go up one grade- rings are worn- if heavy- time for a rebuild- rings need to be replaced. but for the money on rebuild- could find car newer and lower milage

Smoke oil? For what your thinking that is oil? Smoke coming from the tailpipe is not good news, but does not necessarily mean the engine needs rebuilding. First, you need to determine what color of smoke is coming from the tailpipe
* White smoke is caused by water and or antifreeze entering the cylinder, and the engine trying to burn it with the fuel. The white smoke is steam. There are special gaskets (head gaskets are the primary gaskets) that keep the antifreeze from entering the cylinder area.
* Blue smoke is caused by engine oil entering the cylinder area and being burned along with the fuel air mixture. As with the white smoke, just a small drop of oil leaking into the cylinder can produce blue smoke out the tailpipe.
* 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.


If you confirm us that is oil smoke, check and keep in mind that the car has many seals, gaskets, and O-rings that are designed to keep the engine oil from entering the cylinder, and one of them has failed. If too much oil leaks into the cylinder and fouls the spark plug, it will cause a misfire (engine miss) in that cylinder, and the spark plug will have to be replaced or cleaned of the oil. Using thicker weight engine oil or an oil additive designed to reduce oil leaks might help reduce the amount of oil leaking into the cylinder.

White smoke from tailpipe, running poorly.


Blown head gasket for sure if its a petrol engine.

If its diesel then its overfuelling.

My 2001 Olds Intrigue had white smoke coming from tailpipe. When bad fuel injector installed, gasoline poured out the tailpipe and stopped when injector blocked off. Now it "misses" and will not run unless...


these cars have what they call dis system. connected to the computer is an e.s.t. sensor, this controls the injectors an spark going to the plugs. the e.s.t reads a magnetic signal from the camshaft. A bad e.s.t. sensor can cause tons of problems. they are a lot cheaper to replace than injectors.

Gas pouring from tailpipe


Make sure you use OEM Injectors. The white smoke might come at a 3.5 from a bad gasket bewteen the intake manifold and the throttle boy or if you have the 3.8 from bad gaskets between the intake manifold and the engine.

Smoke and water from tailpipe


That white color is a tell tale sign of a bad head gasket, when the head gasket goes your coolant mixes with your oil and the burns off causing the white smoke. I hate to give bad news but it's not cheap or easy to replace.

Hope this helps

Most likely it is oil smoke, if the smoke is black, and the check engine warning light is on, it could be over fueling for numerous reasons.How many miles on the engine?

Black smoke from exhaust


hi nishga
im dave; hope i can help

First you need to determine if it is actually black smoke or if it is blue smoke. There are three colors of smoke that can come from the tailpipe. It is not white smoke obviously because that is easily differentiated from blue or black and generally indicates water or antifreeze leaking past the head gasket and into the compression area of the motor. White smoke is the steam of the water/antifreeze being emitted

Blue smoke is caused by engine oil entering the cylinder area and being burned along with the fuel air mixture. As with white smoke, just a small drop of oil leaking into the cylinder can produce blue smoke out the tailpipe. Blue smoke is more likely in older or higher mileage vehicles than newer cars with fewer miles. The car has many seals, gaskets, and o-rings that are designed to keep the engine oil from entering the cylinder, and one of them has failed. If too much oil leaks into the cylinder and fouls the spark plugs, it will cause a misfire(engine miss) in that cylinder, and the spark plug will have to be replaced or cleaned of the oil. Using thicker weight engine oil or an oil additive designed to reduce oil leaks might help reduce the amount of oil leaking into the cylinder.

Black smoke is caused by excess fuel that has entered the cylinder area and cannot be completely burned. 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 heavy fuel odour in the engine compartment. Some of the causes of excess fuel are a carburetor that is out of adjustment which is not likely unless you have installed an aftermarket carburated system on your non-carburated car, a faulty fuel pump, a leaky fuel injector, or a faulty engine computer or emissions sensor. If black smoke is present, check the engine oil 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. Check the above mentioned systems and after detecting the trouble replace the faulty parts and then the engine oil and filter.
