Well here's something new today.

This morning I tried starting the car, but am getting no glow plug light. So I wait about 30 seconds, what should be more than enough time for the plugs to warm, then turn. Engine is cranking but no start. The glow plugs were replaced this August after one failed (they are the original series style).

What is going on? Before it was glow plug lights functioning normally, then no crank.
Now it's no glow plug lights, but strong cranking.
