I know there are similar threads. I knew it was electrical but after checking inertia switch (did have to reset), ignition and ECM relays and fuses under hood I finally checked voltage at coil plug. Nothing on orange/blue which should have 12+ volts. After rechecking all found I missed one fuse in cabin...F92...it was blown. Removed accessories I had tied to ignition 'run' position and replaced fuse and started right up. Can't believe how many fuses/relays are in that circuit, but know where to start next time! Hope this helps somebody...
