Can you pump up the pedal? If so it's a good indicator of air somewhere in the system.

In my experience a bad MC will have a firm pedal initially then slowly sink to the floor as fluid gets around the piston inside the MC.

Yes, bleeding the system is the most likely cause. You may have air at the MC end

Also, check your banjo. If the pedal has wiggle up and down with your fingers, you need Rodney's adjustable banjo

I had a very low pedal with a S10 Blazer master cylinder. I went with a full size Blazer mater cylinder and my pedal was much higher

The S10 MC is a compromise between the high but firm pedal of the full size Blazer MC and the really low stock Fiero MC. I'm guessing the OP's pedal is going to the floor.
