The demon is a 2001 Dodge Intrepid and over the last couple of weeks this forum has been so great in helping me narrow down the problem. So history: the car just stop running while driving. We determined it has no spark. We don't think it is the timing, it has fuel and compression. So before we go to the extent of thinking that we need to replace each of the coil packs, is it possible that the crank shaft positioning sensor could be the culprit? Or are there any other logical ideas? We haven't been able to locate a scan tool yet and it just isn't realistic to purchase one just to repair this vehicle. Thanks for your continued input.
