Floor boards were soaked and wires were corroded. spliced wires together started up and drove fine. next day went to store and it won’t start; one wire came disconnected reconnected and no power to ignition everything else lights up, turn key nothing PSM light is on and service engine. why do I not have power? code read out P0030 02 sensor and heat circuit. I’m puzzled.

Did you reconnect the wire? can you take a picture of it and upload it here? Also, is the security light flashing? Please let me know.
