@drk_u4ria when you "dropped you starter" did you verify that it worked? If you did not have those sparks before, it is possible that you crossed the starter wires somewhere. Watch the positive cable going to the starter and make sure that it does not touch the case or the engine block. It is also possible that you have a short in the solenoid or the starter itself.
