pull the yellow wire off of the starter relay to disable the starter & have a helper hold the key to "start" & you under the hood with your VOM see if the coil positive primary terminal and the blue (OE) or blue/yellow (MP) wire/terminal at the ECU are hot (plus the ECU red/green terminal needs to be hot if 4 terminal ballast/5 pin OE ECU). As said unplug/replug the bulkhead & the ign switch connector if not hot. Holler back.
