Okay: I have an 85 300sd. I am in Colorado and it was cold a while back so I couldn't get my usually dependable diesel to start. I didn't really need the car so I left it sit for a couple of days until I found out from my neighbor that starting fluid might help. (He is a backyard mechanic.)

I bought the starting fluid, sprayed a bit into the air filter and the car started right up. The problem is: The glow plug light doesn't come on anymore and the car is hard to start even when the weather is warm.

I then read the starting fluid can and it says "Do not use with engines that have glow plugs." oops. No more trusting the neighbor.

Did I fry my glow plugs and if so are there any tricks to changing them?

Thanks
