No Communication with Scanner/Code Reader
To make a long story short, my Trans Am isn't running right and when I hooked up my simple code reader to it it power on but said no communication. I think took it to the dealer and when they tried to hook up their big money proper scanner, it also had no communication.
I checked the wiring beforehand and don't see any burned through or broken wires.
Dealer said they thought I needed to get a new computer. Over on the LT1 section they seem to think it wouldn't be the PCM. I took the PCM out of the car and it's a remanufactured one, not the original.
Also, the guy had an aftermarket tach wired into one of the wires coming out of the PCM harness. I removed it and covered the little slice in the insulation that the wire splice thing had made.
How can I go about seeing if I really need a new computer or if there is something else causing no communications?
Thanks in advanced for the help guys. Don't want to waste a bunch of money just throwing parts at the car but I do want to get it fixed.

I'm thinking that I might have to replace the computer just to know what I'm working with.
