I have a 2000 Hyundai and it keeps fouling the plugs with gas. If I renew the plugs it starts and runs fine but after a day or two it wont start again. What can be causing this?

Possible causes include a bad O2 sensor, excessive fuel pressure (bad fuel pressure regulator or plugged return line), leaky fuel injectors, dirty air filter or restricted air inlet, or a defective coolant sensor that prevents the engine management system from going into closed loop mode
