Just fried my computer?
Thanks to your troubleshooting document from Andrew
Mattei I finally got the link working. But it took so long to do that while it was 50% done uploading the pcm to the laptop... the battery died on the laptop and went into hybernation. I tried starting the car afterwards and I had no fuel pressure, so we plugged in the laptop w/ an extension cord and i cant read the pcm anymore, is it fried?

Yes, you cannot pause programming for longer than I believe 400ms before the computer is fried. If the laptop went into hybernation, then the battery would have been low, it would not have been dead.
Or, did it simply hit a screen saver? On one of my laptops I found in BIOS a setting to turn the screen off after 2 minutes of inactivity while on battery, this means keystrokes, not program based.

I had the same sort of thing happen. I was reading the pcm with LT1 edit and half through I received the error "lost communication".I tried to read again nothing , also tried Tunercat to read (needed for truck) nothing.I tried to start it and all it did was crank over.I though I kill the pcm also but I disconnected the battery for a couple of minutes and the car started right up.

The PCM is definetely toast. The chips have to be pulled and reflashed. Let me know if you need some help with that. I fix/socket them and also have working ones in stock if you need one quick.

If you were reading then its OK, pull the PCM_BATT fuse and plug it back in, or unplug the battery.
You say uploading, that means sending data to the PCM, which means writing not reading. Reading would be "downloading."
