i recently got a Katana from a friend that has had it stored for about 2 years. it ran fine when he parked it and it has sat ever since. when i got it, the battery was dead and the gas tank was nearly empty and the gas was bad. i put a couple gallons of good gas with a carb cleaner additive in the tank and hooked it up to my battery charger that has a "start" feature and cranked away. it would sputter and run for a short period of time and then die. after 5 or 6 times of this, it wouldn't fire at all. i figured that the spark plugs were fouled from the bad gas in the carbs and let it sit.
i then bought new plugs for it and while i had the tank off, check for spark...nothing. none of the 4 plugs spark at all. the coils are getting power, but i'm not sure how to check (or test) if they are getting a signal from the ignition module (black box aka ecu). also, i'm not sure how to check/test the crank sensor to make sure it is giving a signal to the igntion module. anything else i can test?
in summary, the engine cranks and cranks, gets gas, but no spark.
are there any common problems related to this? any simple fixes? any other ideas will be greatly appreciated! i'm a fairly competent mechanic, so don't be afraid to get technical!
