Left front brake cylinder not getting brake fluid when brake pedal pushed

There is a module between master cylinder and wheel cylinder (inline), it has 3 lines exiting it. Front line and back line has fluid that comes out when brakes pushed, but middle line (goes directly to wheel cylinder) doesn't have any fluid coming out when brake pedal is pushed. All wheel cylinders, master cylinder and brake lines replaced April 2016. All wheel cylinder brake lines have been bleed, except left front. The ABS light is not lit and I have a strong peddle, just can not seem to get any fluid to left front wheel cylinder. Pads were replaced but fell out of calibers (left front only) because caliber will not compress due to lack of pressure to it. I was getting lockup on right front when brakes applied, so I pulled fuses for ABS, and I stopped getting wheel lockup but puzzled why the is no pressure getting to the left front and pressure is fine to all other wheel cylinders.
