Starts but wont run after ignition switch is returned to the run position from the start position.
The problem is that when you have the switch in the START position, you are getting power to the ignition system, but not when in the RUN position. Most likely causes are a bad ignition switch, a faulty aftermarket alarm system [if it has one] or a bad ballest resistor wire going to the ignition coil's + terminal. You need to break out your test light and start checking to see where the fault lies.
