need help bad!! STILL no spark to coil!!!

Probably this extract of the DuraSpark circuit will help:



The (-) on the coil is not a ground, is the collapsing pulse receiver to have the coil generate the spark, it doesn't go to a ground. You can check the pulse with a 12vdc test light, while the engine is cranking, it should blink, if it doesn't,... need to go back to the module, wiring, connectors or pick-up coil. GL

I remember you posted that diagram in his other thread, but it didn't seem to help.

Yeah, I noticed and remember that too.
Provided voltage is ok, module passes (had it tested), the pick-up coil is OK, no connections or wiring problems are present, coil pulse is not present; the only small detail that could be overlooked is the small ground reference point/connection that is located in the distributor (ignition system ground).

The other option is to go through all the testing steps of the system found in http://www.autozone.com/servlet/UiBroker?ForwardPage=/az/cds/en_us/0900823d/80/15/0c/13/0900823d80150c13.jsp.
