Topic 3: Distributor Will Not Fire
If you are experiencing a no spark problem with your new DUI Distributor, the following information will help you check and test the installation, connections and components of the unit so that you can get your engine running and start Driving Under the Influence of more power!1. First and foremost, check the 12 volt wire that you are using for power to the distributor. This wire should be a minimum of 12 gauge and have no resistors in line. Make sure your 12 volt wire is fully connected to the “BAT” terminal, which is the terminal located on the front right of the cap. Also, make sure the three wire harness is fully connected to the three terminals behind the BAT and TACH connections. WARNING: If the hot wire is connected to the “TACH” terminal, damage to the module and/or coil can occur.
2. If all of your connections check out good, then check your battery voltage as you are cranking the engine. Since the DUI is a high performance ignition system it requires more voltage than a standard ignition system. If your battery voltage drops below 10.5 volts, this is not enough power to get the distributor to fire. This condition can be due to a weak or old battery or you are using a hot wire that has a resistor in line. Use a volt meter to test the hot wire while someone else cranks the engine over. If the voltage drops below 10.5, check your battery. To make sure it is not the hot wire, run a temporary jumper wire directly from the positive side of the battery to the distributor. If the distributor fires using the jumper wire, run a new hot wire from your switched 12 volt source to the distributor.
3. A bad ground can keep the distributor from firing as well. The distributor grounds itself to the engine when installed. Make sure your ground to the engine block is secure. If the intake and/or the hold down clamp has been painted, remove any paint from the surface where contact with the distributor is made. To ensure a good ground, a secondary ground wire can be attached to the distributor by connecting a wire anywhere on the housing and running it to the chassis, body or negative side of the battery.

I just went though this..I changed the module 4 times on a speed shop dizzy..had the alt. tested checked ground staps and voltage..still could not figure it out...replaced the dizzy and have had no problems since..soma aftermarket parts are not built for the long hual.. I think it was shorting out on the pickup assembly under the rotor..

Papajoe logged off two minutes after he advised that he'd contacted the MFR about modules (Post #30) almost 14 months ago, before 36 sedan posted his good info, and hasn't been logged on again since. Hopefully he figured out his problem a long time ago
