getting fuel .but im not getting spark. i grabbed the coil its self and it was nothing there after i saw no spark from the wire to the manifold. so i started searching for voltage. this is what i found. on the coil there is 2 plugs. one is black and one is gray. the gray only has 1 wire on it im pretty sure. well there is 12 volts on this wire. but however when the engine turns it drops to about 9. the other plug on the coil has no power. what can i do/ look for. into getting spark. thanks guys.
