It acts like the battery is dead but its not. The power windows do not work nor do the power locks. My radio works and the convertible top works also, I am also able to move the seats back and forth and the rear spoiler extends and retracts. My key fob has not worked for some time now, but i always opened the car manually and never had any problems with it running. when I turn the key to start the car all the lights in the dash lite up except the check engine light, and nothing happens, no crank.
This is what I have done so far.
Replaced the battery with a new one. even though the previous tested good. 12.37v
I replaced the key switch (electronic part), no change.
bypassed the clutch safety switch, no change
Took the driver seat out, inspected the area for water or moisture, there is none. its completely dry.
Checked the fuse in the immobilizer unit and its good.
put a multimeter and tested the voltage on both sides of the 15AMP fuse in the immobilizer and only got a reading of .56v, no sure if that is correct or if it needs to be 12v.
checked every fuse in the fuse panel and they are all good.
checked the relays in the rear trunk and they are also good
I suspect that the power is not reaching the immobilizer unit. I tried connecting my OBDII scanner and it says it cannot communicate with the car. I always used this scanner in this car with no problems and I checked it in my other car and works fine. Also the LED indicator light on top of the dashboard does not work, and with the key fully opened the check engine light does not light up.
Is there anything in between the key switch and the immobilizer unit that can have a fuse or can cut off power to the unit if defective?
Is there anything that I am missing here?
Any help with would be greatly appreciate it.

There should be a relay for the DME
Sounds like the DME is not getting power.
On my 2000 3.2S it is in a holder behind the trunk liner on the drivers side.
8-10 bucks at O'Reillys I would look at that
just reread your post and see that you checked the relays. sorry.
I would check all the factory grounding points make sure they are all good.
