Need Ignition Help
 

OK Friends I need somemore help!!!!!!
I Have a 93 S10 Blazer with 4.3 Vortec (W) enigine that has no spark.

I have 12V at the Coil and tru to the Ignition Control Module. I also Tested the Pickup and while turning over the engine it was giving me .5volts.

I then tested for Ignition Coil Switching Signal with an LED test tool there is where things just don't add up!

with the red lead from the LED tester on + battery post and black lead on the white lead from the Ignition Control Module the LED is lit but once I turn the ignition switch on the light go's out. and when I crank the engine it dosent light up at all.

Can you tell me what is bad? LOL

PLEASE
