I have a 1998 Dodge Grand Caravan Se 3.3L,
I purchased it not running. I think it has a ground problem. When I hook up the battery the dash lights come on, the heater, rear wiper control lights flash. When I crank the motor I get no spark. If anyone has heard of a common ground problem please post a response with the location of the area to look in.

 

the heater rear wiper control lights mean it needs to be calibrated.. look up on here how to calibrate it.. it will tell you.. dash lights will comeon when the key is on as a self test.. the spark is what you need to worry about... that other stuff wont keep you from starting it..
