Tried everything lol.

My scanner wouldn't link when a fuse blew on the PSi harness. Changed the fuse and everything worked.

What about all your grounds? How is everything grounded?

Do you 'feel' the other relay click when you turn the key?

I have grounds all over the place. I will see what PSI can come up with later this week. Hopefully it is my wiring or something easy. They will make sure the ECU is programmed to my specs.

Heavy grounds from the battery to the block and body? Ground strap from the block to the body? ECM needs a nice clean ground.

I have a heavy wire straight to the block. then Ground to the Subframe. I have sold mounts on the subframe.

Only thing it could be maybe I need a better clean ground to the body.

The ECU is grounded to the body.

This might be a clue......

You need to constant hot to the PCM, fused from the battery. The you need your keyed hot(which you have already verified). Once you plug in your scanner and turn the key, you should be able to connect to your PCM. If not, either the OBD connector is not wired correctly, or you don't have computer power, i.e., computer not booting up.

Your OBD connector should have a hot wire from the keyed hot and then a ground. The other wire goes to the PCM. You can check the pin with a volt meter once you turn the key on and see if there is power at the OBD connector.

That is what I would check first.
