Ok, update. Forgot to mention I had already tried removing all components and also reseting SMC. Nothing. Not even a click sound of the relay when touching the power button. Found the service manual here: http://tesselator.gpmod.com/_Text/MacPro_Service_Manual.pdf


On page 120, it states:

Power Supply Verication

To power on, the computer’s logic board requires “trickle” power. If the system fails to power on, rst reset the SMC as described in this chapter. If the computer still doesn’t power on, follow theprocedure outlined below to determine whether the issue is related to the power supply.

LED 7 should be green when the DIAG_ LED button is pressed, indicating that the main power is OK and within regulation.

What is odd is it does not state what the source of problem is if there is no trickle power. I don't have trickle power, so is that logic board, power switch, or power supply?

Removed power supply and tested the fuse. It is OK. Found attached image of power supply pinouts. From this, can anyone tell how to test the power supply (short jumpers?)?
