Remove the cap and see if the rotor is burned through or the carbon button in the cap is gone.If those are both good chances are the ignition module is bad or the pick up coil is.You can ohm the pick up coil leads but I don't have exact specs I would guess between 600 and 1000 ohms would be ok.Zero ohms or an open would be bad for sure.If that checks out and you have power and ground at the distributor I would replace the ignition module.Some auto parts stores can test them on a machine they have.
