My OBD2 port used to work and now it doesn't. It is not my scanner because it still works on my wife's escape. Any ideas?

Here's the Pinout to check for voltage.

No voltage, red to pin 16, black to 4. Nothing.

Head up to the sticky which helps locate wiring diagrams, find yours, and start tracing back to from the port.

On ME7 it is fused right off the main power buss, but your 1998 might be different

same fuse as for the lighter.
