Ok heres my problem. My engine cranks but it wont fire up. I just checked the spark plugs and there is only one that is giving a spark (top left cylinder). I have a seloc book for my engine and it says that it should give off a blue spark but my engine is giving off a whitish yellow spark. Does this mean anything and what are the possibilities for the other spark plugs not sparking?
