I'm aware of this. I stated it didn't stay on as to point out the pump came on to pressurize when the car was turned on (not started), and did not continue to run as to burn itself out with the car being un-started/turned off.

If the ground circuit is corroded/breaking down, then this could result in a very hot ciruit inside the pump motor. The "easiest" way to check it would be to voltage drop from the grounding point to B-. You should get no more than .2V. If it is higher, like .6. or worse yet something 1V+, then your ground wire is bad and requires repair/replacement.
We took apart the original pump and it's quite seized. No idea on pump #2 as that was exchanged under warranty for #3. No fuses have blown (have been checking). Will check the voltage readings soon, thanks.
