Pig Latin - Help me make my code work

1

I know this is a poor code but this is what I could come up with. This code passed all tests except the third one (“glove”). Please, don’t provide me a totally different code or an easier one, help me to change my current code.

function translatePigLatin(str) {
  var str1 = str;
  var str2 = str1.charAt(0);
  var str2_1 = str1.charAt(1);
  if (str2 == 'a' || str2 == 'e' || str2 == 'i' || str2 == 'o' || str2 == 'u') {
    var str3 = str;
    var str4 = str3.split('');
    var str5 = str4.push('way');
    var str6 = str4.join('');
    return str6;
  } else if (str2 !== 'a' || str2 !== 'e' || str2 !== 'i' || str2 !== 'o' || str2 !== 'u') {
    var str7 = str1.split('');
    var str8 = str7.push(str2, 'ay');
    var str9 = str7.splice(0,1);
    var str10 = str7.join('');
    return str10;
  } else if (str2 && str2_1 !== 'a' || str2 && str2_1 !== 'e' || str2 && str2_1 !== 'i' || str2 && str2_1 !== 'o' || str2 && str2_1 !== 'u') {
    var str11 = str;
    var str12 = str1.split('');
    var str13 = str12.push(str2, str2_1, 'ay');
    var str14 = str12.join(''); 
    return str14;
  }
}
translatePigLatin("consonant");
