1994 Oldsmobile Ciera Shortage with Parking Lights & No

Hello,

I have an Oldsmobile Ciera Cutlass. I inhertieted it and it once had an alarm system on it, but since disconnted years ago. The parking lights stay on now when the car is turned off, due to the remote missing on the car. This remore also locks and unlocks the doors. I have had to discconnect the battery for some time now every time I stop, otherwise the battery will go dead. Now the car will not start at all. Any advise woul be great.

Thanks, Eric
