help, fans wont turn on.

Okay, so I bought a 93 v6 3.4l camaro about a year ago and I have had sooo many overheating isues its silly. I have replaced the the radiator, the thermostat (2 times), the temperature sensor, checked the fans their relays and fuses, made sure I have sufficient coolant in the engine. Still my fans wont turn on to bring the temp. down. It has been suggested to me that the pcm could be to blame, but o dont think so....any ideas?

Disconnect the coolant temp sensor used by the ECM, the fans should turn on within a few seconds.
Also, disconnect the pressure sensor in the high pressure A/C line and short the connector pins with a paper clip or piece of wire. The fans should turn on almost instantly.
If both fail and you are positive the relays are good, one more thing to check is the fusible link for the fans located in the area shown in the following picture:


If the link is also good, it is almost certainly the ECM.
