Hi ___?___,

Welcome to Brickboard.

Don't throw parts before diagnosing the problem.

OBD port 6 (ignition) is kaput? That's bad news.
I had my OBD port do that and found that the bullet connector had failed
I'll give you repair/parts details later.

The female connector at port 6 can be dislodged with the neoprene or
whatever that stuff is to hold the female connector so when you plug the black
lead into port 6 it makes a connection.
Don't take the connector apart yet
First look in port 6 and see if the female connector looks like the one in port
2. See if port 6 connector is pushed down , loose, floating free.
see if you can jury rig the black lead to the port 6 connector and maybe
get OBD report?

Let's try to get a readout from the ignition ICU to point to the problem.

While you have the hood open, confirm that the ground wire/s to the intake manifold are solid and not loose or broken. Those are key for the ICU.
(It looks like maybe only one signal ground for REX)

Post back, Bill
