I used OEM parts. I tested the BPT valve and it checked fine. Here is what I got as an answer from an online mechanic:

Hi Keith,

With the engine running, ground the white/blue wire at the EGR Control Solenoid. You should hear it click and the EGR should activate. If it does, ground the white/blue wire at terminal 103 of the PCM. if everything works, the PCM is bad. If not, there is a break in the wire between the EGR-CV and the PCM.

There should be battery voltage, with the key on, at the black/white wire. If not, check fuse #9 and the wiring between the fuse and the EGR-CV.

If all that checks out, replace the EGR-CV.
------------------

Now, what's the "PCM" and the EGR-CV? Is that the same as the control selenoid? This test he gives seems pretty specific and what I may need. if I can't figure out where all these emission controls are it's off to the dealer. I wish I had a detailed emission schematic of my emission controls. The Haynes manual is absolutely horrible and vague and does not get into the 1997 truck much at ALL. Let alone where terminal #103 and fuse #9 are!
