I've wired a GM HEI module into my car. The distributor is a stock 2.0 unit, converted for use with the Ford Duraspark module. I cannot get a spark. Suspecting a bad pickup unit, I tried shorting across the sensor pins of the HEI module as I had read the unit would operate with breaker points. No spark. Tried another coil. No spark. Bought another module, no spark, using either the distributor or shorting method. The module is grounded and wired properly. Any ideas?
Having hit a brick wall with the HEI, I tried a Ford Duraspark II module. It will spark only when the ignition key is turned on or off. Testing the pick up coil, I get 2.0 ohms. Checking another pick up coil I happened to have, get 2.0 ohms. Pick up coil lead to ground gives infinity. The distributor (including the electronic pickup) worked perfectly with a Duraspark module when last used 20 years ago. What's next?
