why do the antilock,oil dash lights stay on when i try to start my car.

Hello, I would verify that you have proper charging system power -- check it for reference voltage and charging amperage. If you do not have sufficient power from the charging system, odd malfunctions may occur and the battery may not recharge properly. If you verify the battery and alternator and charging system components including cabling are in perfect working order, then you would need to address the specific components -- the anti-lock braking system and the oil pressure specifically. However, I'm guessing that you have a charging issue. Good luck.
