Default The LS400 that died! FML

Alright so here's the story. My LS is pretty low on K Sport coilovers...I hit a bump at maybe 30-35mph and my car shut off like it stopped running, so I threw it into neutral and started right back up. That was weird right? Not 5 minutes more down the road, I came to some rail road tracks, sped up and hit another bump and it did it again, though this time IT DIDNT START!

So there I was on the side of the road. Called my buddy and had him look up diagnostics, jumped the TE1 port to the E1 port, recorded the CEL flashes. Code 14 and 15. Which is both ignition coils...

Do you guy's have any ideas?
It's pretty weird to have both coils go out at the exact same time but it could happen I guess?
I need help!

First thing that comes to mind is you might have rubbed through your fender liner in to the harness wiring. Check over the drivers side front tire to make sure that's not the case.

Cars a 92 LS400. What could I have rubbed on the inner panel? And should I start taking off the fender well panels?

I also have no idea what an ignitor is. I knew since both of them quit at the same exact time it had to be something else

Can you post a picture? And it's just a box? Does it have a cover on it? This could be my problem because the engine only shut off when I hit those two bumps which were pretty big on the right side.

Also, how do I test it?

Is it like the fuel pump relay box?

ALSO I believe I found my problem. The tire wore through the fender lining and theres a bunch of bare wire showing. I touch it and it arched. How do I go about repairing this?

I have disconnected the battery. And my dumb infinity wheels have a locking lugnut I dont have the key for. Going to go look around for one.

Need some dire help! I'm not sure how to repair this! Should I get that section of the wire harness? I dont know what to do.

Yeah, just take it slow and solder new wiring in there, cover it up nicely and keep it protected. Relocating the harness since your car is so low (I'm assuming) is key otherwise it'll just continue to eat it and the problem will repeat itself.
