I think I know exactly what happened here. I had the car in a body shop not too long ago. When I went to pick it up, and started the car, the radiator fan came on right away and was always on as long as car is in ignition or started. I asked the guy what the heck is going on but he was clueless. I did some troubleshooting at home and found out that he drove a screw that secures the left fender to the body under the hood right into the wiring harness shorting some wires together! This is by the left headlight and FAN controller/regulator. So I fixed that but didn't check the fuses. As a matter of fact pump worked after that - i know because I could hear it at start up. I think it was slightly damaged from the short but not enough to blow, but eventually after some time blew.
