The wire goes from positive battery terminal to the F region. i currently have a wire running til the kit comes in the mail. But does this mean i will need a new fuel pump or just wiring wrong?

You are not protected by any fuse with the wire connected. Plus it will drain your battery when parked. This means you have a bad fuse box.
i have disconnected it only when i need to go somewhere
I just experienced this same problem. Left me stranded on mountain late at nite.
Thankfully tow truck came out and saved me. Towed me 60 miles home.
My mechanic was able to figure a quick and simple bypass that seems to be working so far. Do not know if it it safe or if it will continue working. Will keep you posted.

Just order the kit works like a charm.
I wanted to post my experience with this issue and remoting the relay as Medtro's kit does, because it might help someone down the line that is tearing their hair out like I was a few days ago.
I bought Medtro's kit when my 100 first started having the immobilizer issue. Installed the kit, everything was happy as a clam for about a month. Then all of the sudden one morning, the issue came back. Only this time, the immobilizer light wasn't blinking with the key in, the truck just didn't fire. For fun, I swapped in the original relay and a fuse, the truck still didn't start, but this time the immobilizer light was blinking with the key in. I wrote that off as my relay was shot or something, and got out my multi-meter and started checking the fuel pump, wiring, all the ignition stuff, CAS, etc. All was within spec, which made sense the truck showed no symptoms up to just not starting.
Finally, out of curiosity and desperation I stuck the multi meter on the A and B pins shown below (where the EFI fuse goes, and how Medtro powers the relay with his kit). I got 8.18v, it should obviously be 12+. I ended up having to add a line direct from my battery and replace the wire from A to B to the remote relay, and now it's working great. I guess the short in the fuse box eventually gets worse. Hope this helps someone in the future. It's a head scratcher.

Connect a wire from battery 12V post to the F terminal (see picture below), then try to start the engine. This kit will not help if the engine doesn't start with the above wire connection (assuming the battery is fully charged). This is the kit you need if the engine starts.

Can anyone follow up about having to route a line from the battery? And supply some photos? I’m likely buying the kit but want it bulletproof.

I know a few has done this hopefully they will post pictures. It is basically instead of connecting to the EFI fuse slot, you connect the wire to the positive battery terminal.
Its been over 5 months since I installed the immobilizer and no issues. Fires up every time like a charm.
Ok, so my 2000 LX470 just had this issue and now it’s not wanting to start at all. I turn the key all the dashboard lights come on and then when I want to start there’s nothing, no cranking. How can I fix this on my own? What troubleshooting steps should I take. If someone can let me know since I need the vehicle and can’t wait until the part would get shipped. Thanks
