Got a 2002 dodge grand caravan. Came in for overheating. Replaced bad water pump. When I backed the van out. Noticed the speedometer arm jumping. Hooked up my snap on scanner it will comuncate with the ecm. But not with trans, body controll module, air bags, cluster. It says is key on like i'm not getting power but just to the ecm. Don't know what to try next. Al fuses are good
have the same problem?
