dEAR Sir
my car smell like gas. I have had a new fuel pump put on. If the car is running and standing still, the fumes are really bad. What could it be

Running rich:

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.
