you can try to put it in neutral to see if its the safty switch, or locate the starter relay and check the ignition switch

Tried in both neutral and park. Same result - will not crank. I cannot seem to find the starter relay - I think it is integrated into the TIPM. Thanks for your suggestions. I need to know what wire on the ignition switch to test. And is the ignition switch in the circuit before or after the neutral safety switch and the TIPM? That might help diagnose where the problem is.
