Turn ignition to run, find your Ecu and count the "blinks" in it's window.
there will be a 3-4sec delay between 'codes' if there is more than one problem.
Did this pop up after you 'worked on' the car? You could always pull the neg off the battery, touch the brake peddle to make sure that there is no voltage hiding anywhere in the system. That should clear the ECU. If it comes back, start over and count the blinks and post back here.
I'm supprised that the 'codes' aren't stickied on here for each opperating system somewhere.
