    no luck yet.. I ordered a new ignition module for $18 which are notorious for going bad. There is also an issue with the trigger wire on the starter but I think it is this ignition switch.

    With the key on set to run, do you have power at the safety switch?

    Park/Neutral safety switch at the transmission. If the key is cycled to run & power then goes live on the body side probing at the appropriate wiring, then that should rule out the ignition. Moving on to check the circuit relating to what you just then checked brings you to the starter & solenoid.
    If the signal wire is active when you enable the ignition & the starter does not engage, that indicates the solenoid is not responding. With some physical strikes to the solenoid, the jarring might provide a temp fix.
