Question about Cadillac STS
Power steering systems are actually pretty basic as far as operation, however pain in the **** when it comes to leaks. As read, you said you had leak in what you thought was in your power steering pump, and then found out it was the hi pressure hose that was leaking, Unless your car has some type of fuse that controls it in your fuse panel. (check owners manual, to see if you have a relay type of fuse that controls the electrical circuit that triggers the pump) if so, it could of got blown. However, I believe this is what has happened. When you had a leak in the power steering, you thought it was the pump, so you replaced the pump, which of course pump was probably bad because of lack of fluid circulation with a leak, it instantly will dry out, from high heat of friction from barrings, metal on metal with no fluid. Now, that being said, you put new pump on, but sense the leak was actually off the high pressure hose, means it is highly possible that your new pump, by driving it for even 10 minutes, with the leak of high pressure hose, could of cause new pump to burnout. So, at worse case example, you have burnt up new pump, because of the time you replace the high pressure hose might of already done the damage to the new pump. But, before you go that route of replacing again, the new pump, check all your wire connections that are triggering the pump. Make sure all connections are hooked up good, and making good contact, as even the pump has to have power supply to trigger it, and check to see if inline fuse (if has one) is good and of course as said earlier fuse box to see if as a safety feature, sense would be low on fluid with a leak if it blew the fuse that controls the electronics that go to the pump , make sure it is good. I hope this helps you in the areas to look. Places like AUTO ZONE, can look up your car and let you know for sure if your pump is controlled by a separate fuse and where it would be.
