Answers :

Can you remember if your key had a little black square near the grip end of the key? if it did then that is exactly your problem the car's computer system checks for the signal from this chip when the car is started and if not present will cut the ignition power and fuel pump circuit. if you used a screwdriver on the ignition you'll probably need to replace the switch and have a key made at the dealership, altho unless the car is in really good shape it may be cheaper to junk it and get something else...sorry
