It seems that the timing(of the sparks in the plugs) are not tuned. So basically a tune-up should solve the problem. Also get the distributor checked too, it might not be getting the proper current fro the induction coil responsible for generation of accumulated charge, so that the spark produced at the tip of each plug is same for all cylinders..........soddep

Excessive white smoke from tail pipe


White smoke:

White smoke is caused by raw, un-burnt fuel passing into the exhaust stream. Common causes include:
·Incorrect fuel injection timing
·Defective fuel injectors
·Low cylinder compression

Low cylinder compression may be caused by leaking valves, sticking piston rings, ring wear, cylinder wear, or cylinder glaze. When white smoke occurs at cold start and then disappears as the engine warms up, the most common causes are fouling deposits around piston rings and/or cylinder glazing.
Continuous evidence of white smoke indicates a mechanical defect, or incorrect fuel timing.

How about a valve problem?

Do a Cylinder Leak Down Test

Do a Smoke Test ,on the Intake, for vacuum leaks

Exhaust Blocked?

Fuel Pressure Checked at Motor?

Incorrect valve clearances


Raw petrol means no combustion in the cylinders or fuel is flooded. Check the spark plugs and ignition spark first. Noise in the cylinder head could mean engine knocking due to oversupply of fuel or unburnt fuel causing higher pressure in cylinder.

Dose a 2000 taurus lx have a single or dual port fuel injection and is the coil pack for one cylinder or is it a pack for all cylinders?


depends on the type of engine. DOHC engine has coil on plug ignition system where the OHV has a coil pack with spark plug wires going to it. Both engines only have one fuel injector per cylinder.

What will make the make it flood its self


An engine will flood if there's too much fuel going in because of a stuck choke, a bad spark not igniting the fuel, failed temperature sensors, bad fuel regulator, timing...the list goes on.

The amount of fuel delivered to a properly functioning injected car is determined by sensors mounted throughout the vehicles air intake system. These sensors work together along with the ecu to control the fuel / air mix delivered to the cylinders.

We would need to isolate the components that have impact on the duration of time the injectors stay open. In troubleshooting it is often best to work backwards.

1. Injectors - Are they leaking? 2. Pressure regulator - is the pressure at the fuel rail the right pressure?? (40psi for most fuel injected cars) 3. TPS- throttle position sensor- is this reading accurately...there are several different styles of these 4. Air flow meter - these also come in several varieties varys from mass air sensor / simple vane meters. 5. during startup there is a seperate circuit called the throttle bypass valve - this also may not be functioning if the flooding is occuring rapidly during startup. If the car starts and runs for a while than floods. this is probably not the culprit. 6. ultimately the ECU could have a problem as it is the link in the chain that ties everything together....though not likely. Any of these these would have the potential to flood a vehicle if they were not functioning properly.

This is just a list of things that could cause your car to flood!

97 kia sephia smokes when first starts, smells like exhaust smoke


Black smoke is fuel.
Blue is oil.
White is coolant / water.

Fuel is caused by timing and cold start system and requires some discussion to clarify.

Oil burning only on start is caused by failing rings on your cylinders. Oil then enters the combustion chambers and burns when you start the engine. If it continues to burn when running in particular when you accelerate it will also indicate ring/cylinder failure. It can also be from a failing head gasket where oil travels from the lubrication system into the combustion chamber. Some of the anti smoke additives available at the auto supply store do help.

I doubt you are seeing white as you say is smells like exhaust. White is coolant in the combustion chamber or exhaust system.


Hope this helps you.

White smoke from tailpipe, running poorly.


Blown head gasket for sure if its a petrol engine.

If its diesel then its overfuelling.

No you need to bring your number 1 cylinder to to dead center, ( T.D.C. ) this will align your crank shaft then you can adjust your you cam marks. You will need to be sure that your number 1 cylinder is on the firing side and not the exhaust side.
