Does the engine crank with the starter, is there fuel pressure and spark to the plugs? Such failures are unlikely to set a code so you will need the basic trouble shooting skills needed to eliminate them as a possibility.

Be sure your battery is connected and fully charged before attempting to scan or you could possibly make the problem worse. Don't leave the battery charger connected when scanning.
Also, don't try to start the car while scanning unless the scanner tells you to. Hook the scanner up to the ALDL connector located as stated in the previous post, then turn the key to the run position only (not the accessory or start position). Just read the scanner manual completely before attempting a scan.

The car died on the way home from work, like it ran out of gas...had just left the filling station, after several attempts she refired and I made it home. The next day it only turns over, reaching under the opit$park, feels like a greasy film on it. Did not wash the motor, and have no leaks. Thanks, Jimi

You didn't say if you are getting fire to the Opti from the coil or from the Opti to the plugs. Could be a bad coil or ignition control module that's mounted with the coil on the front of the passenger side head.
First check that there are no wires or connectors loose that could cause the failure.
Follow up with us as you check things mentioned.

The things you say would be relevant if we were talking about flashing a prom, but we're talking about scanning for codes.
