1988 Oldsmobile Ciera Not starting. Dont know what's wrong

I have a 1988 Oldsmobile Cutlass Ciera 6cyl 3.8L. When I turn the key it starts to turn over fine for the first second. After a second passes the starter slows way down. There fore it won't start. I have no idea what the problem is. The plugs are fine they get power. I was told by a friend that it might be a ignition coil. Then again I was told that my car has no ignition coil. Others have told me it was my computer. I have no clue I need some help here
