I've made a mistake once before where I've left 1 of the 2 diagnostic wires plugged into the connector that you use to check for codes. If you've recently checked for codes and left the wire till plugged into the connector, that maybe the culprit.

It says in the manual not to start your engine with the diagnostic wire plugged into the connector but it doesn't say the car won't start... It will start and just keep flashing.
