Boy i messes up big i fried my PCM

[ZF5]

I was working on my 99 PSD and i was trying to figure my wierd injector knock out. SO i unplugged the DP tuner and just to see, and sounded alright. Without thinking, i plugged the chip right back in AS IT WAS RUNNING and shut the engine off, and now the wait to start light, fuel pump, no power to the other side of the glow plug solonoid all dont work, i put the code reader on, and said no connection, and turns over but no start. So i fried my computer im guessing... I have one from a 7.3 van, and figured on using it for my truck. Would it work? any suggestions or am i just a complete idiot lol I had an expensive brain fart.... IDK what to do now... any ideas? I also have a FICM module too but i think its the pcm. The chip wont even light up anymore. Did i hurt my chip? Will the van, actually an ambulance, pcm work?

that sucks, try taking the chip back out and see if the truck will start without the DP in

edit: hopefully you just fried your DP tuner which would be good because you can still drive your truck stock, unless you did burn up the PCM
