Ok, let's back up to the beginning here.
The car was running prior to what you did albeit it would die after revving it slightly correct?
Next...quit banging on the CCRM for now. It may not be your problem anyway and by doing this you can cause more harm than good.
When you turn the key to run (not start) do you hear the fuel pump prime for a few seconds and then shut off? You should be able to hear it turn on.
Just for informational purposes, when the car is running and you turn the wheel to one lock or from lock to lock the pressure inside the rack builds a great deal of pressure in it. The power steering pressure switch will increase the idle slightly to compensate for the pressure which allows the car to continue running so if the switch is bad then it could cause the car to die. Now in the Gen II with variable assist, I'm not entirely sure about. The pressure switch may be built into the variable assist for all I know.
The squealing you heard was more than likely your power steering pump or belt and was probably caused from the pressure that was built up inside the pump. Make sure you double check the fluid level and the belt if you haven't already.
If the car dies when you turn the wheel all the way to lock you could be looking at a new power steering pressure switch or something with the VAPS. But first check your connections to verify that they are plugged in and that the connectors are clean.
Now the car won't start at all. As Chris said, verify fuel, air and spark. You might also consider running KOEO tests as well to see if there are any codes stored in the EEC.
I'm not exactly sure if the power steering pressure switch and/or the VAPS carries vRef or not, but if they do and if vRef is not present (if it's shorted to ground) then it will not allow the computer to do what it needs to do and you won't get any fuel pump prime or pressure.
Checking the fuel pressure by manually making the pump come on is great, but if the computer can't or won't make it prime by itself then you have another electrical issue that needs to be addressed. But it would be a good way to rule out functional issues with the pump itself. So we need to know if the fuel pump comes on or not when you turn the key forward to run.
Please list everything that has been done to your car recently, most problems will be in the areas that you have been working on. I know this from my own personal experience this past summer. Let's start with the basics here first and then work out way up to the more complicated shhhtuff.
In the mean time, I'll do more reading on the Gen II VAPS system to see if I can learn more about it so I can give some better educated replies. I don't want to give out wrong information.
Also, what motor do you hear running when you turn the key to on? The fan motor by chance?
