Help!!!???
I have a 91 allante, pump motor runs constant... have replaced the whole abs unit per mitchells pinpoint testing... no codes coming from abs, but red brake light on constant plus message center displays abs disabled/traction control disabled. If pump motor is bad will it run constant due to lack of power to charge ac***ulator??? is there a spec for pump output to test??? any help would be greatly appreciated...

not good at all .. that is a $200 to $900 pump. dont let it run non-stop.

replaced whole ABS? when?

mitchells pinpoint testing ? explain ...

the details are unclear .. please clarify.

but you got a couple of potential issues ...
- the ABS relay that controls the pump - good luck, not avail except at salvage yards - good news is that usually when this fails, the pump will NOT run.
- the ac***ulator failing to keep a charge - $250 rem
- leak in high pressure hose - $75 rem
- pump seals are done, pump - $200 to $900
- low fluid
