Have your dad turn the key to "On" not start while you sit at the back of the car near the Fuel Door. Do you hear the Fuel Pump engageing? If not, chances are it's burnt out and needs to be replaced. It's not uncommon for the Fuel Pump on our cars to die, mine went out at 88k long and reliable miles.

Go to the CCM and test a light blue/orange wire. Thats the wire that activates the relay. Green/black wire coming out of pin 11 of the CCM is your fuel pump power wire. Check that. If all else fails, make sure you have a good ground at all locations.
