If a car that turns over but won't start, then you have to diagnose the causes for this problem. Here's what you need to do to find out the cause of your problem. Make sure that you have enough gas in your car. Try to refill your tank when it is no less than one quarter full, or you risk getting stalled or stuck somewhere. Verify that the battery has a full charge. Check to see if your fuel pump is turning on. This can easily be done by putting your key in the ignition, turning it to the "on" position. Finally find out if the engine is getting gas to it and determine whether the spark plugs are firing. If there is plenty of gas but no spark, the engine will crank but not start.
Its water in the gasoline mixture. When the car is first started, the engine temperature is not high enough to evaporate the water in the gas, so the water travels out the exhaust pipe
The fumes are the burnt exhaust gasses.
Check the tailpipe for contact with the body. A loose hanger that holds the exhaust up may be sagging. The movement of the motor starting will jar the exhaust system.
Normally, The engine will not start.
the engine wont start
You probably have a little oil seeping into the combustion chamber while the engine is off. Once you start the engine, this oil is burned and causes the smoke you see.
If water comes out after the car is totally warmed up, it has a blown head gasket. Most cars spit water on start up due to condensation in the exhaust after you shut the motor off and it sits and cools.
When you start the car, the hot exhaust condenses on the interior of the cold exhaust system. This is normal for a few minutes until the exhaust system warms up. If the water smells and taste sweet, and you are continually adding coolant, you may have a blown head gasket. If this is the case, do not continue to drive the vehicle as serious damage will be done to the engine.
It's burning oil, does this happen when you first start it or does it do it all the time ? if only when you first start it, you could have bad valve guide seals and then they need to be replaced, if it does it all the time the engine is running it may be time to rebuild the engine.
That is called condensation. When you start the engine the exhaust system/pipes are cold. When the heat from the engine exhaust passes through the exhaust it makes it sweat. That is normal.
Start your engine and look at the exhaust. If there is a lot of white smoke coming out, you have water in your gas. You can also place an empty cup in the stream of the exhaust. If water droplets appear in the glass, you have water in your gas.
The question could be improved to read: "Why does steam come out of the exhaust when I first start my vehicle?" Answer: condensation. When you shut-off your engine and the the exhaust pipes cool down, water will condense on the interior surfaces of the pipes from the warm air in the exhaust pipes. This water pools there until the engine starts up again. Then, it starts to evaporate and exits the tailpipe as steam. After all the liquid water evaporates and the exhaust pipes get too hot for water to remain on their surfaces, the visible steam will cease to emerge from the tailpipe. So, no; it is most likely not from a blown head gasket or a crack in the engine. If you are not losing coolant then all is well, drive happy
