Went to start it yesterday, and it didn't want to go. Rather cool out, as it was just above freezing. Turns out the glow plugs are pooped. I think it's because I don't wait for the timer to shut them off when it's warmed a slight bit, and it's too much heat for them. The timer won't run when the engine is warm enough, but will come on up to that point, even though it will start ok.
These ones only lasted about a year. Good thing I ordered a second set when I ordered the first ones.
