What is the "modulator" you are referring to? The ignition module perhaps? Do you mean the starter spins but does not engage the flywheel? Have you tested for spark? What is the fuel pressure?

You should be able to get an ignition wiring diagram from any Chilton. If one doesn't show up here quickly I'll look in one of mine and see if I can find a 4.9.
