i have a 2002 lexus ls430, somebody ran a screw into the wire harness, all the wires appear to be ok after taping up the bare spots and all the fuses are good, it will crank but won't turn over and the headlights won't work
I’ve checked all the fuses (I have found) and they all check good, the screw was ran into the main harness, as I said earlier, all the bare spots have been taped up
I had similar issues this past week when I had my battery replaced. When the new battery was put in the car was turning over but not starting. Also had issues with no lights on dash cluster. I ended up having the following blown fuses.
1) Amp battery fuse in the fusible link block
2) Alternator fuse in the fusible link block - Brought my dash lights and all interior functions back
3) INJ fuse in Engine room No.2 - This was the fuse that actually got the car to start
4) ETCS fuse in Engine room No.2 - After the car started I went to take it for a test drive. I would put the pedal to the floor and the car would barely move. Replacing this fuse fixed that issue.
5) Radio fuse on passenger kick panel fixed issue of the nav system saying "Audio Off"
Check engine light was still on after everything was fixed. I ran the codes and it ended up being a code for the throttle sensor which I had fixed by replace the ETCS fuse. I cleared the code and now everything seems to be back to normal.

Thanks for all the info guys, I’m bout to head back down to the shop now, just out of curiosity, what will the condition of the horn tell me? Also, I have checked every fuse (in all 5 locations) and all r good🤷*♂️
The horn shares the same power source, "FL MAIN 2.0L", with the headlights, EFI (injectors), and others. You had mentioned that the headlights do not work, and the engine does not fire. If your horn also is down, then most likely their common feed is the culprit.
Excellent info, thanks so much, I didn’t make it to the shop yesterday, I’ll use this when I make it down there, hopefully this afternoon, thanks again.
I believe it is inside the Fusible Link Block (next to the battery) for the LS430. Please take a look at the link below for a DIY to replace this fusible link for a Toyota 4Runner: https://www.yotatech.com/forums/f116...cement-228307/
The Fusible Link is designed to melt and disconnect wires downstream from the battery under over-draw condition. You will read on the 4Runner forum that some people argued about replacing this fusible link with a regular larger wire. Imagine if that were the case for you and the fusible link did not melt, the screw that penetrated the wire will short the battery directly to ground and turn the length of wire between the battery and the screw into a heating element. Given enough time (in a few seconds), it can potentially set something in the engine bay on fire.
Again, very good info, thank you, I have the cover off to this fusible link block but there is nothing labeled “fl main 2.0”, does this link have a fuse or is it just a meltable link? I notice in the diagram you attached, there is no amperage listed for this link. Thank again for all the good info.
This particular Fusible Link, "FL MAIN 2.0L", is a specialized wire harness, or a "meltable link" as you called it. Please review Post #12 above, and follow the attached link to a DIY on a similar Toyota vehicle. There is a picture of the fusible link shown on that forum.
