HEI issues!

Moffet,
The FIRST thing to check is that in crank & run you are getting 12v to the 'B' terminal on the module. Might be slightly less due to voltage drop/how you wired up, but close to 12v. If 12v is missing, then you need to check the wiring. If 12v is present, it narrows down the suspects. There is a drawing on the web where you disconnect the p/up plug & ground either the G or W terminals [ drawing will show which terminal ] & you get a spark. That is a 50/50 test. No spark, module is bad. Getting spark is good, means module is likely ok, but not a fail safe test, as it does not test the input from a p/up.
Congrats on going to HEI, it is a brilliant design.
