Hi and welcome to JustAnswer,

Thank you for the question and your patience. Should you still need assistance for information purposes only...

Initially, let's do / review the basics. Proposed preliminary tries (if have not been done):

  • • inspect the battery, its ground lines and/or check/clean the battery cables + terminals, connectors and wiring as a preliminary consideration. Have the battery externally charged and then LOAD TESTed (even if new/charged and just for the purpose of eliminating it as a suspect);
  • • locate the starter relay:
  • • jump the 2 big terminals of the starter relay. Expect a big spark. If it does not crank, then possibly a cable and/or terminal issue;
  • - if it does crank, then ensure that its black/white wire has a good ground connection;
  • - and that its yellow/red wire gets an +12V when pressing on the starter button;
  • - if there is good ground and IGN+12, then there should be a click from the relay;
  • -no click, ground or +12 missing;
  • - there is a click but starter motor would not spin, then relay would be suspect;
  • - no +12, then check the wiring, connectors and switches;
  • - no good ground connection on the green/red wire, consider test hardwiring a second ground line.
