Hello. My name is ***** ***** I will be helping you today.

This is normal operation. The glow plugs stay "on" till they are warm and you are supposed to start it when the light goes off. If you dont the PCM keeps them warm by running short cycles on them till it decides you arent ready to start it yet and gives up till you cycle the key again.

Let me know if you need anything further and please be sure to rate my service so I get credit for helping you today. Thanks

Ah, im new to this diesel, thought i was supposed to wait until it went out completely so ive been waiting til the flashing stopped. Having hard time starting it lately, actually havent been able to start it for a week. Cant find block heater plug in either so Ive been dead in the water, and wearing out my battery charger, lol

Make sure you glow plug relay is working. Just buy a spare and try it ... if it makes no difference throw it in the glovebox for when it does go bad,

And get a block heater on there or even get one of the dipstick ones... something.
