Did it not throw codes with the failed glow plugs? My DMax had one die and only way I knew was the code. Replaced all on that side of the engine while there, but I've read that the DMax isn't really sensitive to NC type cold temps.
In hindsight, yes. My tuner prevents the check engine light from ever coming on though (it seems) so it wasn't a constant reminder.
I thought that the cold weather starting issue was a powerstroke thing until I talked with Del about it this year. It wasn't until this week that I put the glow plug issue together with my starter issue.
Also in hindsight, I thought this job was going to suck, so I've been putting it off. It wasn't bad at all, should have done it a year ago!
Time will tell if all is good!
