Uh oh, my Genesis 4.6 won't start after spark while changing plugs!

[mtrot]

Well, I've messed up pretty badly. While trying to remove the 3rd plug on the passenger side, the socket extension made contact with the one of the electrical cables that comes from an electrical supply box on that side. (I took the cover off of that box because the cover was making it difficult to get the socket and extension down into the plug port.)

Anyway, there was a big spark and crackly sound. I was about finished changing the plugs, so I went ahead and finished with that.

But now the car will not start.

Some lights and functions do work, while others do not. I checked the two fuses that are located near the positive battery terminal, but they do not appear to be blown. There is a fuse associated with the cable that sparked, but I cannot tell if that fuse is blown.

The brake lights, steering wheel telescope and tilt function, fog lamps, LED accent lights, interior trunk light, interior "dome" lights, and power fuel access door all work. The actual headlights do not work, nor do the emergency flashers. When the door is opened, the interior lights do not come on, despite the DOOR button being depressed. Does anyone know if there is another fuse somewhere that is supposed to blow if something like this happens? Any other ideas? Thanks much.

Try jumping the car off if it doesn't seem to have enough juice to crank it.
Or does it turn over easily and just won't start?

Thanks, it doesn't even try to crank, doesn't make a sound. But it has the power to run those other things I mentioned above. I will say, the cable where it sparked looks sort of "fried". I'm wondering if no electricity is getting through that cable. I'm going to take pics and show them to the dealer shop.

I would at least try to jump start it, the battery could possibly have enough juice to burn a light or some lights and yet not have enough to turn the motor over. I have experienced this before on another vehicle and on my Genesis I had some weird issues that disappeared after I replaced my battery. Just a suggestion, I am not a mechanic by any means! Trying it would just confirm I believe whether it is the battery or not.

Bit of a long shot, but my 2009 shop manual shows that there's a 30A fusible link for the starter ignition circuit between the battery and the starter solenoid, in the E/R Relay fuse box.

Odds are more likely that you cooked something inside that pass-side box.

PM sent.

Thanks, I had the car towed to the Hyundai dealership on Thursday, where it still sits untouched. They tell me that they only have two Hyundai technicians and that they have two engines and two transmissions ahead of me. Yesterday, I stopped by a highly regarded independent imported car repair shop who can look at the car Monday, so if Hyundai still can't tell me on Monday when they will get to my car, I may have it towed to the other shop.

Okay, so the service writer from the dealer shop called today and says the culprit is a 125 amp fuse. He couldn't tell me where in the car the fuse is located. Apparently the fuse costs $5, but with the diagnostic fee and tax, I'm looking at about $150. I guess it could be worse.

So good news, the fuse did it's job.

Yup, the 125A fuse was one of two that sit inside that electrical box that sits on top of the right front fender well. I had looked at that fuse when I was trying to figure out what was wrong, but I couldn't see anything wrong with it. The tech said it was really hard to see the damage on it. Oh, well, at least it's fixed and wasn't something worse.

Was this a 12.5 amp or 125 amp?

Based on the description, it is likely actually 125A. Since some stuff worked and the starter didn't, it's probably a main branch fuse which is why it's so large.
