at first the check suspension light came on last saturday. rode around for a bit turned the car off and it went off. thursday it came back on; stop to go to store with key off the pump kept running. restart and the light went out. get to work (about 15 minutes) it comes back on. leave work it comes on,the pump is not running, and it's sitting on the ground. before this happened there was no blinking lights, and it maintained ride hight always . should i assume that the pump is dead?
