For the first time ever on any of my vehicles, the glowplug light failed to light on my coupe the other day, the thermometer said 35 F, car had not been started in a week. I turn the key off and try it again, still no light, I turn the key off again and turn on the dome light, cycle the key on again and nothing, no dimming.

Well this engine runs great.. lets see what happens... I had to crank it for maybe 15 seconds till it coughed once then died, then cranked another 10 seconds till it fired up and idled. While I was cranking the oil pressure came up after about 5 seconds to almost 2 bar.

I like the fact that I had oil pressure before it fired, and I wouldn't have a problem if I had to crank the car for 3 to 5 seconds until it fired, I don't know if it would cause undo wear on the starter or gears, or too much unburned fuel in the cylinder?

I'm not necessarily advocating this... just want to discuss the pros and cons of a longer crank time.

FYI-This thread is not about fixing my glowplugs.
