Hi Everyone, i wanted to test to see if my glow plugs were getting power today and here's what I found. I ohmed all the glow plugs and they were all good. Before I go on, i want to mention that my glow plug light only comes on for one second when i turn the key on and then goes out. I hooked a test light between the glow plug harness and ground and turned the key on and got nothing. I then unplugged the coolant temp sensor (which supposedly forces the glow plugs to get power for twenty seconds) and turned the key on again and still got no power to the glow plug harness. i checked the fuses on top of the battery and they are fine. Where do I go from here? Is my coolant sensor bad? Is the glow plug relay bad? What number is my glow plug relay? Any help is much appreciated. Thanks a lot
