YO CAR HELP IS NEEDED, so recently I've been having problems with my oil pressure and also my starter, most of the time I start my car I have to try like 3 or 4+ times to start it - and most of the time it will only start if I give it gas. Earlier today, when I got off work it would not start at all, so I had to leave it at work and am going to get it properly looked at tomorrow. It's a 1998 Chevy Malibu, any idea what it could possibly be and possibly how much replacing it would cost me?
