Put this together for a friend, still troubleshooting root cause but thought I would share. We have a gremlin where for some reason the LR3 occasionally isn't calling for a start condition to trigger the starter motor relay. If you run into similar, here is how to bypass the starter relay to trigger a manual start.
------Under the hood, passenger side, open the battery box cover and the fuse box cover.

By wiggling and pulling up, remove the relay labeled “START” or “SM” on the fuse box diagram.

Place one end of the jumper wire into the circled slot labeled “1” on image.

Turn vehicle key all the way on, then momentarily insert the other end of the jumper wire into the circled slot labeled “2”. Be ready to immediately remove the jumper from slot 2 once vehicle has started!

Then remove from slot 1 as well, replace starter relay, covers, and vehicle is ready for operation

 

so every LR3 owner needs a little jumper wire in their glove box ? haha
