Do you mean when you turn the ignition key it wont turn? Most car doesn't crank on its own. If it doesn't crank, how could it stay running? Tell us little more in details. We love to help and learn from your experience too.

turn the key that courtesy alarm doesn't even chime but the clock in the dash stays lit maybe it oculd be the aftermarket alarm or radio that was installed could you tell me where to find wiring diagrams?

Sometimes installing other electronic devices might affect the car. Double check your ignition system or kill switch associated with the radio.

When you turn the ignition to on position do the dash lights go on? If you get no juice alarm is armed...Try turning the key in the passenger side door..That resets it sometimes....It sounds more like a bad ground wire or something...
