Hi, I'm Tim and I'm an HVAC expert here to help answer your question(s). Please provide all the information I ask for since I'm not onsite. At the end of our dialog you will be asked to rate my service, but please wait until then and all your question(s) have been answered satisfactorily. Thanks for your business!

Try stripping a small section of the black and white wire going to inducer motor, set your voltmeter to volts AC, and see if you have 120 volts across these wires on a call for heat.
