Hi,

I'm new to diesels and am not sure where to start.
I should note that this is a non-turbo motor.

One day leaving work, the glow plug light didn't illuminate.
It was a little hesitant to start, but not as much as now.
The next day it was back to normal. It stayed this way until as few weeks ago.

This symptom started all of the sudden. It used to start instantly.
One morning it took a couple of minutes to start and has been the same ever since.
Once it's been driven, it will start instantly - even if I screw up and forget to wait for the glow-plug cycle. Otherwise the engine runs perfect, good power, smooth idle.

Should I start at the glow plugs? Is there a way to test them?

Thanks in advance for any help you can provide.

Bryan
