either way the motor and pump where beyond help so i bough a complete refurb unit and installed.
now everytime i install the unit i bleed the system using the bleed tool you connect to the solenoids and manually bleed the system.
i start the car and hear the motor kick in/prime and turn off after 3/5 seconds, no lights on the dash. i drive 3 miles down the road and the motor dies and burns out. i have now had the motor re-built 5 times.
i am starting the think there must be another issue, maybe ayc computer or wiring but have no idea, anyone ever seen this and can you point me in the right direction?
If the motor is burning up like that, you're going to have to start chasing electrical.
It sounds like there is a short somewhere and it is activating it when it shouldn't be and burning it up
