I have a 2004 jeep grand Cherokee Laredo I'm not able to get it to start or even turn over. I had a cracked connector and replaced it but then the obe I replaced it with cracked now I'm on my 3rd pair of connectors in 2 days and it still won't turn over. At first it seemed like it was the connectors because when I changed them my truck started but now it won't. It's getting power from the battery because my radio and all my gauges work. Does anyone have any idea what the problem could be?
