Recently my xfire has developed a problem of not starting (won't turnover at all, lights radio etc all work). This has occurred so far when car has been sitting in garage for couple days. I leave it alone for couple more days and try again and presto it starts fine, and will continue to start 20 to 30 times before it happens again. It has done this with both old battery & new battery (same cca as oem). Any help with diagnosis would be greatly appreciated. Thanks.
