Cold Start Issues

My 2002 F-250 has developed a cold start problem after the engine light came on. Checked and cleared the codes and they returned. P0672 thru P0678 all are glow plug circut on the drivers side of engine. I have checked the wiring connector on the glow plug harness. Where do I go from here? Farmteck

Did you actually test the relay, or look and see if the wires looked fine? My truck wouldn't start after sitting all night in 20-30 degrees and my relay was shot. Replaced and now I don't even have to plug it in, but i do anyway.

There are a few articles to actually test them.
