I changed my big 3 kit on my 2002 accord 4cyl. When I went to start the car there was power, but as soon as I tried to turn it over there was a pop and now there is no power what so ever to the car. I ran all of my new grounds from where the original grounds were & All my grounds/alternator wire connections are good, checked with multimeter, my 100amp fuse from the main fuse box for the battery is good, my 50amp ignition switch fuse is good. Idk where to go from here, any suggestions?
