Very hard start
Hey all,
Went out of town for a business trip over the last week and left the truck parked at the airport. Came back and weather was about 35 degrees, and she did not want to start. I had to cycle the plugs and try to start it 7 or 8 times before she fired up, and once she fires up she runs extremely rough for about 10 minutes. I have had this problem a few different times. In weather from 22 degrees on up to around 45-50. Could this be bad fuel or could this possibly be my glow plug relay going bad? The truck has 34,660 on it, and I wanna get this fixed if it is a problem. If this is normal, is it bad to cycle the plugs that many times? I've read in a couple places that it might damage the tips.

You may have a couple glow plugs that are bad or possibly a bad relay. Your batteries sound like they are still good if you are able to make that many attemps to crank it. But it would be worth while to check them. I doubt it's the fuel if it runs well after it's warmed up.
That seems to be too few miles for glow plugs to go but it's possible. I'd think a problem with the relay would be more like it.
I remember when my 95 model did the same thing. I had a couple bad glow plugs but I had around 80K on it.
I just sent this link on checking glow plugs and the relay that Joe wrote to another guy with cold cranking problems. Check it out.
