Question about Cars & Trucks
Yes, repair the alternator wire. The pcm does not control alternator output, it only uses and monitors it. I don't know if it is a problem, but maybe from the bad wiring you found may have affected it. Don't know who told you to replace the pcm, but think I'd get a second...well, a third opinion.
Sorry I can't help you more, good luck.

i had this exact same problem ... under the hood onthe left side of the firewall where your starter solenoid and fuseable links are there is a little container type thing that holds a 20 amp fuse that fuse is probably blown the little container is on the firewall right below the fuseable links

Have you resistance checked the injectors. If the resistance is wrong the pcm will shut the injector drivers down.

Damaged harness. Inspect the wiring harness for damage. If the harness appears to be OK, disconnect the PCM, turn the ignition ON and observe a voltmeter connected to the EVAP Canister Purge solenoid driver circuit at the PCM harness connector while moving connectors and wiring harnesses related to the EVAP Canister Purge solenoid. A change in voltage will indicate the location of the fault.
The numbers below refer to the step numbers on the Diagnostic Table.
