1992 Dodge Dakota • V8 4WD Automatic •

Hi, I have a 1992 dodge dakota extended cab 4x4 with 318 engine. Was having trouble with the brakes and replaced the master cylinder, rear wheel cylinders, rear brake lines, rear shoes and front pads. Bench bled the master cylinder before installation then bled all lines until clear brake fluid with no air. When engine is off the brakes will pump up and hold but when the engine is started the brake pedal presses all the way down with no brakes. The anti lock light is on as is the brake light. I tested the power assist and it holds vacuum. The only thing I haven't checked is the control module, is there any way of testing this? Any other ideas? Thanks
