I recently experienced my glowplug lights not turning on and off and subsequently the car won't start. If you turn the key and the glowplug lights turn on and off the car will start but if it decides not to turn on the starter will just crank but the engine will not fire. Sometimes the green and red lights (anti theft device?) on the rear view mirror will start flashing. I checked all the glowplugs from the relay and they all are fine with readings of 3-4 ohms.I also replaced the alternator and had the battery checked and it was good. Could this be an indication that the k40 relay is going bad? Any ideas?
