    the only thing I could think is the valves are staying open to release comperession.
    Maybe a broken timing chain or belt ?????
    But this should cause some poppin and burpin I would think.

Why is 2003 Nisan Frontier Super Charged truck smoking and 4th, 5th, and 6th cylinders not firing after spark plug change? Put old spark plugs back in no change


If the engine is smoking and you have misfires on three cylinders, this is not a good thing. The best course of action at this point would be to pull all the spark plugs out and perform a compression test to help evaluate the extent of the damage.

1987 olds regency ninety eight has spark, fuel, but will not fire .


The spark and fuel both get there reference from the crank shaft sensor , so as long as the crankshaft is turning and the sensor and module are good you will have spark and fuel, it sounds like one thing you are missing is compression I think you should see if you have lost a timing chain, does the engine seam to be turning over at a very fast speed? pull a spark plug and check for compression.....SORRY TO BE THE BEARER OF BAD NEWS

Car just stopped running, it turns over but I


could be the timing belt. they should be changed every sixty thousand miles. If the car sounds like it spins over real fast could be the timing belt. Take off the timing belt cover to look at it or pull a few spark plugs out and check for compression. If you have no compression most likely is the belt. If you find the timing belt did break you have even more trouble because you have what is called an interference engine which means if the timing belt breaks the valves will get hit by the pistons and bend them then you will need major engine work. Although it could be your fuel pump too. check for fuel pressure and also check to see if you have spark at your spark plugs. so many different things can cause a car not to start.

Cylinder 3 will not fire. running lean...


If you look at your engine as a group of one cylinder engines, it will help. What is not happening in that cylinder? is the injector allowing fuel to enter? Is spark happening? Is the cylinder itself in good condition ? ( are valves opening/closing, is compression good) One of these items is missing there...you need to find out what and why.

Well some spark plugs are better than others for certain cars and Autolite plugs are not recommended for hondas. As far as oil showing on the plugs the more likely indication is that the valve guides have gone bad on the engine. A good sign of bad valve guides is if the car smokes more when you first start it after it has been sitting overnight. The Proper way to test for a sound engine is to do a compression test on the cylinders, that way you have a percise check on the overall health of the engine(for a mechanic to say otherwise is not a good sigh). If the car does have bad valve guides it is not threatening to the healh of the engine. You biggest problem from faulty guides is that it will cause you spark plugs to foul(oil soaked) and not fire as well as it should, In my opinion and without having the results of a compression test I think that valve guides is you proplem and not a "bad engine". The reason for your car smoking more after the new plugs is that they are able to burn the oil and you older autolites could not. My biggest and most important recommendation is that you never go back to that mechanic again.
