brake trouble

I had too replace a brake line on my 93 Sonoma, no leaks used a double flair kit, I've bled the brakes multiple times in order and still have no brake pressure while truck is started, starting to get agitated, how can i get air out of master?

I replaced a brake line once & the increase in pressure created another leak in another line. Another thing is that some cars have a starting point & finishing point. I would always do the fronts then the backs. Sometimes they get bled around the horn. Other times they get bled in an X pattern.

The fact that there is pressure when the car is not running could point to a bad power booster. Bleed the brakes when the car is off.

Not sure how yours is configured, but most braking systems are actually divided up to front and rear chambers of the master cylinder. If you are bleeding the brakes and press too hard on the pedal, the shuttle will move to one side and block fluid from that side. You will have to re-center the shuttle to regain fluid movement.
