Car won't start. Could miss Carlisle! Please help.

I know this was sorta said but it bears repeating; Start the car and keep the key in the START position. Keep the engine running with the gas pedal just as you normally do. The starter has an over-running clutch on it, and this will not hurt it. Keep it running this way for maybe 10 seconds. This will prove that that the ignition and fuel systems are BOTH normal.
Now, relax the key switch to RUN.
If the engine stalls, then, there is something wrong in the run circuit. It could be the ballast.It could be the sw. Or it could be the wiring between the sw and the ballast.
