GM HEI Module Questions
I decided to upgrade to a TFI coil and the HEI ignition module this weekend, following the wiring directions on gofastforless.com and from Ford Six Performance. I've hooked everything up, triple checked all my wiring, but I'm still unable to get the engine to fire with the HEI module. The TFI coil works fine with the Duraspark module, but when I switch the distributor's wiring harness to the HEI module, it won't fire.
Anyone have experience doing this mod? At this point, I'm seriously considering that my new HEI module may be faulty - I have connected the two leads from the distributor and the two leads from the coil, have everything grounded correctly, but still cannot get it to fire.
Any suggestions?
