Just wanted to add this:
I had the block heater plugged in overnight, and is started great! I'm thinking this eliminates almost everything but the glow plugs functioning right.
I guess my question is, without any codes present, is replacing glow plugs the right next step? If the controller was bad, would that for sure set a code? Just don't want to wast money on plugs if that isn't the answer.
Yes, you'll find codes in the ECM for bad glow plugs or a bad controller if either of those are the issue.......pull your codes for sure.
Mine will start rough without being plugged in too but I also know I have 3 bad glow plugs (there are codes stored for all of them).
