Symptoms indicates the problem is due to the ABS master pump. When the pump is ubnable to hold pressure, the brake pedal would sink to the floor when depressed with ehgnine running.

Remove the ABS relay and use a fused jumper wire to bridge the 2 larger terminals to activate the pump to see if the pump motor works. If it is seized, the pump would have to be replaced. since the pump requires, it most probably needs to be replaced sooner or later.

Hey im having the same problem on my 1994 honda civic cx. I just bought it, it had a bad cv axle and caliper. Replaced them both and now i have very little brake pressure when i start the car. Before i start the car the pedal feels good and firm from bleeding it and once u start it, it looses alot of pressure. I can still stop but it comes close to hitting the floor by the time it starts to stop. I dont remember if i said abs cv axle or not does that make a difference? Any info would be great
