If you have an HEI, I agree it could be the module. However, there is a pickup coil around the distributor shaft UNDER the advance plate. You have to pull the dizzy shaft to replace it. I had one of those go away on me before.

If that doesn't work, check to see if the crankshaft pulley is turning or the valves are moving when your turn the engine over. I also had a crank break right behind the timing chain gear and the timing chain no longer was turning, you could have lost your timing chain. This usually results in bent pushrods for the valves.
