Long story short, I had the Grounding System sit right on top of the fuse box, which mean I mounted that thing right on the battery clamp, today I tried to open the fuse box, then I have to removed that thing in order to open the fuse box, suddenly I drop that thing on the battery positive terminal, I had that thing caught on SPARKLING soon that thing touch the battery positive terminal, I removed that thing immediately and tried to start up the car see anything wrong, car just won't started, I thought some of the fuse may pop, I inspected both fuse box, one inside the car and one at the engine bay, non of the fuse were pop, I really don't know what have I done to my car. PLEASE HELP, I appreciate.

 

ouch..
did you check voltage on your battery?

 

you probably fried the ECU.
****. this is not good

 

+1

 

Do you get any power inside the cabin? What does the volt meter next to your oil pressure say?

 

Lesson learned, electrical currents provided via grounding kit do not enhance performance of a vehicle. However it seems odd that something like that could totally short out the ECU even though that is quite a possibility. Got Warranty?

 

NO power period.
Just replaced new battery today and still no power period.
Still running warranty.

 

change everything to stock and send it to dealer!

 

There is more than one fuse leading to the ECU. I'd check / recheck them.

When you put the key in and turn it to on.. do you see a check engine light? If so your ECU is getting power, if not... then no power to your ECU.

What is "that thing" that you dropped?
