I just swap my old swap into a hatch so now trying it out and then i floor it from 2nd to 3rd now im in third gear and as it goes up to about 6500 the car shuts down im i try turning it on and the car is dead, so check the fuses and the ecu one thats under the hiid is blown so i pay mind and i try again same thing happen it blew can somebody shine some light

 

check and make sure you are running the right amp fuses, check all your grounds are connected and in good condition, go over all plugs give em a light push to make sure they are all connected

 

More details, have you been messing with the ECU wiring? Mods, etc?

It sounds to me like you have a short to ground, or possibly something wrong with your voltage regulator on the alternator.

 

thanks guys there was a cut on the wiring and it was touching
