78 F-100 No Spark...help

The truck used to start right up no matter how long it sat. Went to start it last week and no go. I replaced the Ignition switch and Modual (the big alum box one.) Plugs,wires, rotor and cap. Still no spark. Can anyone tell me what to look for? I hooked up a test light to the coil and get a jump everytime I turn the key so I'm assuming the coil is good. Any and all help would be great.Thanks, Whiskers
