im confused my your thread. what help do you need? how to delete it? how will your ECU know what the temperature the coolant is to adjust your fuel for warming up?

I meant delete the post. I found the coolant sensor. Unplugged it to test glow plug relay, found that the relay was bad. Did not reach anywhere near 12V.
