I was thinking the abs computer first. Have you had the system flushed or perhaps there is air in the line. If the offending brake line is free of air and there is no leaks then I'd have a look at either the abs computer or the pump you mentioned. Usually the abs pump needs to be cycled to properly clear the line of air.

Did you change the left front brake hose? The rubber one between the caliper and the steel line.

all lines are new, and bled, only thing that isnt new is the abs pump itself
