Thing has to crank for a solid 3 seconds than turns on . Sometimes it just cranks and doesn’t turn on and I have to turn back key wait a couple seconds and than it turns on . First time it did that and I got it to turn on . I turned it off and back on (2-3 second start) . Turned it back off and did it once more just to ensure it was good and it started on the first 1/2 second like nothing . What could this be ?
