Hi, my name is ***** ***** will be assisting you today. Sorry for the wait, I had posted a question earlier on here and it didn't seem to go through. In order to give you an accurate answer, I will need some more information. Was the ABC pump replaced for the same symptoms? Did you replace it or have a shop replace it? During replacement, was the suction restriction valve activated and the fluid reservoir slightly pressurized in order to prime the new ABC pump? If this is not done, most of the time the pump will not prime on its own and will cause these problems.
