i was told that the (DEM) relay is bad, or it is known as the module relay. i have a 1997 jetta gl, where would i find these relays? the car fires and it wont start, it has plenty of spark, if you turn the key to start it and let the key back it will give a sputter becouse of the voltage malfuction. what else should i check after you tell me where the relays are so i can check them?
