I don't think it is the glow plug relay but I'm not sure. It seems to work fine some days and some days it does this. Any thoughts would be appreciated. Thanks,
test the glow plug relay first, but make sure to test it when it is acting up....if that passes, let me know, your PCM or IDM relay could also be causing this.......but i would almost bet that when it is happening the glow plug relay will test bad........
