I recently put petronix ignition in my 396 camaro. It was running great. Now when I turn the starter the engine seems to fire up but as soon as the key rests in the "on" position (after cranking the starter) it goes dead--no fire. Do I have a bad ignition switch? Problems with my distributor or coil? Do I need to install a tremec 5 speed? (just kidding but I'm looking for any excuse to upgrade to a 5 speed.) Thanks for your advice.
