what wiring could go wrong if the car wont start using the key but when trying to start it with an override starter hooked up directly to the starter it finally fired up.....the relay that i installed for the megashifter is clear and when i turn the key foreward i can see a part of the relay move... and also when i turn the key i can see the temp gauge move...so does anyone know what could be wrong?

any help would b great...thanks
