You could take the cover off and look for fried components. You could also send it to DP Tuner and they could do a stock flash. If they could not program it that would be a sign it's bad. I don't know if they have any pcm diagnostics. You should check with them. I just had to replace mine because the postal service lost it. I paid $150 at a junk yard. You could also try carparts.com. You'll need the pcm code if you replace it.

Cheak these fuses as well, Fuse#s-6,28,24,27.23.17,12,2,18,15,10,19,29,14,16,4,26,8, 13,CB25,22,21,20 all these fuses are feed by a fuseable link. Fuseable link A and J will be a 12 ga Gray wire.
Would also cheak Batteries, Disconnect them from each other and then cheak.

Well Guys, I plugged the pcm back in and it was the same, plugged in the edge evo and it programmed the pcm back to the stock using the hex file saved on the edge. Dash lit up, fuel pump worked, problem solved. Thanks everybody, it's alot easier to dig deeper into problem knowing you have people like yourselves there to lean on. Cheers P.S. I'm guessing I should take it in to get a re-flash done?
