no pressure in brakes after bleeding

I capped the rear brakes at p.C. Valve (derby car) then replaced the brake line from p.C. Valve to front driver caliper, bled the system and can only get pressure on pass. Side front, the driver side front just gets air and a little bit of fluid come out here and there but mostly air, then took the bleed screw out of caliper and put it in p.C. Valve and tried bleeding straight from valve, still no pressure straight from the valve, im confused as to what it could be. Can I run two lines from the master cylinder to each front brake? Thanks, dave
