    Parked the runner after a desert cruise. Went to start a week later, did not start (would crank) and started diagnosing. No spark at the plugs, no spark at the distributor, no spark at the ignitor. Tried to jump the plug to get a code reading, producing no codes to read. Replaced the Ignitor and Module.
    have OHM out the plug wires
    Have checked fuses and relays.
    Have checked grounds
    Anyone have any ideas?
