glow plug light

Hi Guys, I have a 91 350sdl and the glow plug light doesn't come on untill the car runs for about two minutes, then stays on for about 45 seconds then goes out. When I start the car I wait about 30 seconds and she fires right up , so plugs must be working. However the remote starter will not start it, It tries to start before the glow plugs have a chance to warm up. Does run rough for about 30 seconds. Appreciate any suggestions where to start checking. Thanks

I've read several threads on this, but I didn't see any where the actually found the problem. So I still need your guys help. Thanks

Possible bad relay and/or bad glow plugs.

I suggest you seek answers in this thread.

Have a great day.

Thanks Whunter. I've order new glow plugs. Let you know next week if that was the problem.

Just wanted to say thanks to Shertex and Whunter. I finally got the glow plugs installed and that took care of the glow light. Thanks again.
