    Curious to know if there are specifac resistance values for an ignition module. Stock distributor from a 1990 EFI 5.7l. I have scored the new MSD dist as stated in an earlier post but want a reliable backup.

    there is no resistance related to the ignition module, like you would see with a coil or such, but I believe places like Autozone can test them for you for free...

    The ignition module has a few dies and components. So probing for a resistance is not likely to work. Yes autozone will test the module. What kinds of problems are you having? I have sent many hours working on chevy tbi.

    If you have a MSD Dist definatly carry a spare module. Been my experence that MSD modules are prone to failure. They dont like heat.
    Just buy a new GM module they are cheap.
