When there are dashes on your odometer the communication from your cluster to your powertrain control module has been lost. The key has nothing to do with that. A bad pcm power relay, bad ground, or a bad pcm (powertrain control module) are the usual suspects. On the passenger side shock tower there is a ground that goes into a small square shaped block that I've had issues with the wire coming out of the block so I just splice in a new wire with an eye terminal to a good body ground and be done with it. I included a wire diagram of the pcm power circuit.
