My sister's car wouldnt start so i went to check it out. Turns out my bro in law put the spark plug wires in the wrong order. so i correct those and it starts but is idleing at around 3k... so i tell me Bro in law to take it to my house. we make it 2 blocks and he decides he wants to put air in the tire. After we put air in the tire the car wont start....Blown 55A fuse...replaced it and it violently blows as soon as i reconnect the negative battery cable.....Any advice on what to check would help...5point0
