1997 Elantra Starting Issue
 

I have a 1997 Elantra 5-speed sedan. It will only start intermittently. It will always jump start (so far). When I turn the key the motor always turns over perfectly. The battery is well charged. If the car starts, it runs normally. When jumped, it runs fine as well. After a drive, the problm starts all over again. Does anyone have any ideas or a wiring diagram I might check?
