Would this fix my 2004 Land Cruiser when it dies while driving and then occasionally wont crank, sometimes wont start but cranks? Used a jumper with starter relay removed and starter is functional. Alternator is new, battery is newish, fuel pump is newish. jump starting it doesn’t lead to it cranking over. When it died on the road today, I did smell a burnt electronic smell near the engine bay fuse box.

Sorry, this kit won't fix any no crank issue.
 
Is this a known problem on a 2002 lx470? If so, I'd like to keep a kit in my glove compartment. PM me with purchase info.
 
@medtro I’ve been having intermittent start issues on my 2000 Tundra V8 that has the same engine (2UZFE). I’m about to throw in the towel as I’ve replaced basically the entire fuel delivery system and ruled out a grounding issue. It will crank and then act like it’s gonna stall for a few seconds, and then it’ll actually start up. Not much help out there or ideas from online or local mechanics.

Is it possible to use your kit on the tundra with the same engine?

No personal experience with Tundra. I helped a shop to build a kit for their customer with 2001 Sequoia in 2022. Start a new technical thread or PM me if you would like to pursue this. I don't want to clutter this thread with troubleshooting posts.
 
Can the top cover be installed with this kit in place? Sorry if that’s been discussed already, I stopped scanning through after about five pages.
 
Question for this. We have a 100 series at my work that wont start. EFI fuse has power on one side, but when key is on, there is no more power. Is that what this is fixing? Techstream cant "decode VIN" and keep getting VIN errors so cant pull any codes or anything. EFI fuse is where things are looking, but not sure if this is the fix for that or its a whole separate issue
 
Ordered, received promptly. Great communication, and shipped with tracking. Installation was simple. I had to draw power directly from the battery, but it's working perfectly. Thanks!
