Question about 2000 Chevrolet Blazer
I connect computer it wont power on and i have tried multiple shop computers and they still don't gain power or even read codes
Check the cigar lighter fuse it is probably blown, that is where the 12v supply comes from, then check why it blew, chances are its a faulty adapter being used in it, cell phone, radar detector, etc, or there could be debris in it a coin, foil gum wrapper, if nothing found replace the cigar lighter

Check all the fuses with a 12 volt test light. Also does the cigar lighter work many times the same fuse that is for the cigar lighter also powers up the obd 2 connector.

No that doesn't mean the pcm is bad. Replace the cigar fues under the hood. That is where the power is supplied to the scanner. If that fues is blown the scanner will NOT turn on. The quick way of seeing if the pcm is alive is just to turn the key on, if the check engine light is on then the pcm is alive, doesn't mean there isn't a problem but means that it is still online.
Check to see what your fuel pressure is at, you need 50-55 psi to even light the engine!
