I've been saying this for two years. I had my first pump replaced under warranty, and have replaced it again since then. Also have done a couple for other local guys.
I don't know about plastic in the pump, but the ones I've pulled down all had the same issue - brushes completely worn out. In a year.
There is a lot of misinformation in this thread, but i'll just add what I think will be useful:
1. The pump does not run when the engine is off unless you jumper across the relay that controls it. HPT cannot command it on with the engine off, only parameters that are adjustable are a min IAT temp, which turns it off if its too cold outside, and an ERT (engine run time) min, which is stock at 10 sec, meaning that the pump turns on 10 seconds after the motor starts normally.
2. The pump does not usually make a clearly audible whine. Especially if you have any modified exhaust. Only way to check its function is to look for flow at the filler neck. Or jump across the relay with the car off, without the engine running you can hear it.
3. Easiest way to check and make sure its pumping, is to add a bit of plain water to the fill neck. It should get flushed out as soon as the pump comes on. If you are looking at it to see if its moving, your pump isn't working. You will know when it comes on. In this same area, every car i've seen with a dead pump will have the resivior empty when the car is shut off, but it pops back up sometimes when you take the cap off. Normally functioning cars don't do that, there is always fluid present.
Thats all I have for now. I'm working on rebuilding one of the pumps, this may be a much more efficent solution in the future.

The noise will vary from one to another, I just brought that up so people don't just listen for it. You can't hear mine over the exhaust. If I take it out of the car and power it in the garage, different story.

if you could get it to run without the car running you would hear it 
i am 100% certain it can run when the car is off. hell ill even take a snap shot of the setup in HPT so you can set it up.

You sure nothing has been changed on yours? I've never seen one run without the engine running on any car I've played with, at least 15 different cars.

Go set your "ERT Min" to 0, flash, and turn the key on.

So my coolant for the ic system is about an inch and a half to 2 inches up the filler tube, when I start the car up, the coolant moves up and down a bit, does that mean its flowing. I will have to climb under the car tomorrow and check it out.
