All of the common-to-injector pin (2 to 3 and 3 to 4) resistance measurements are dead-on 3.5 ohm.
Logic says that it's not building boost because it's not building EBP because it's not getting enough fuel. However, I am definitely getting white smoke and a misfire when I romp on it, which leads me to believe that the injectors are firing at the wrong time. I replaced the CPS with a new Ford unit and there was no difference.
All I have left is to do a compression test, IDM, and maybe the barometric pressure sensor.
I really want to slap another IDM on there and see what happens. AE would be awesome too, so that I can check Barometric Pressure, TPS (Although not likely the issue), buzz test, CCT, etc.
So if you're within a couple hours of Seattle and you have AE or an IDM, please let me know. I'll buy you dinner.

This *might* work in Torque for you to read barometric pressure:

Add it as a custom PID, then scroll down and hit the test button. If you see a response that starts with something other than 7F, it should be working. It works for me on my early '99, and I found it while trawling through an OBS thread on another forum.
For a buzz and CCT test, you might look into Car Gauge Pro. I don't know how compatibility with OBS is, but if you research it and find it to be compatible, it's only 6 bucks on Google Play Store. It is NOT user friendly at all, but I use it solely for buzz/CCT/KEOE/KOER, etc. tests.
