what kind of scanner are you using? what do you mean the screen is "blank"? no scanner should have a blank screen unless the scanner is broke. My solus will show a communication error and even my $40 handheld will come on and attempt to link the say unable to communicate. do you have power at the DLC? is the 5 volt reference present? The PCM is obviously not bad if it runs on starting fluid. Start by borrowing a noid light set and see if you've got injector pulse. If yes, move on to fuel delivery I.E. pressure/volume test. If you don't have pulse, check for a 5v reference at each injector, if yes, check for ground signal. I think you'll find the reference voltage, I doubt the PCI bus would be down only on the IDM. check for ground signal at the pcm with a test light. I think that ultimately you're going to find an anti-theft issue most likely the PATS module shutting down the fuel system. Go run these tests and tell me what you find.
