Q: glow plug symbol flashing without OBDII code

asked by on October 31, 2016

My problems started with my engine light on and glow plug symbol flashing. The OBDII code was P0380 The 50 amp fuse was out so I replaced it. The flashing glow plug symbol remained, engine symbol was gone. The glow plugs had under 1 ohm resistance so I figured they must be good. I purchased new relay and heat temperature sensor. I don't know about the relay but the heat temperature sensor wasn't working. I changed these two but the glow plug flashing symbol is remaining. I forgot to say that the glow plug harness is working fine and it also looks like the previous owner replaced it. Thank you
