Pontiac sunfire starter issues?
Either your solenoid is sticking or your key switch is bad. Test by disconnecting the positive line to the starter (cover the connector with electrical tape to be sure it doesn't contact the chassis), then test for voltage at the S connector on the solenoid. If there is no voltage at the S connector with the key ON (not just when it is moved to START), replace the solenoid. If there is voltage at the S connector with the just the key ON, your ignition switch has failed and needs to be replaced.
