no spark.
 
I was degreasing the motor it stared and ran fine before. now it just cracks and im not getting spark from the lead igniter with coil the black wire ones next to the battery. any suggestions?? any one had this problem before?

It happens alot,and it is because the connections at something obviously got wet.
You can wait around for it to dissipate/dry or try a hair dryer at any connections that look like they could have got hit by water.

You may want to check your CAS(often called a distributor in piston talk) too.2 little screws will uncover the Cas internals and apply heat or blast air in to dry that area off.

You know the old saying "It hurts when I do this?"
Don't Do that..again!
Now you know why guys wipe the engine with a de-greaser and do not like using a hose!

yea i messed up. lol correct me if im wrong but the ignitor and coil with the blue spark plug wires have spark is just the black ones< that ignitor doesnt have spark but it gets 12 volts to the connector .everything leads me to belive that thew coil is bad. the wiring diagram shows a diode on the negative side of the circuit is that the one use to pulse ground. maybe im getting 12 volts but the ground is not bein pulse . idk and the cranks angle sensor is sending a signal sense im getting spark from the other coil and ignitor. the weird thing is that i didnt get the coil and ignitor near the wet.
