will not start after glow plug replacement

[msamwheeler]

Truck was having difficulty starting when cold. I replaced the glowplugs and the glow plug relay with OEM parts. Followed the tech directions and after reassembly the truck will not start. I have checked all my electrical connections and my fuses and everything looks good. Any suggestions?

has to be uvch connections issue or 42 pin connector issue.

I was able to get the truck started after it sat for a while. Not sure why it fired up but now it is running very rough and the service engine light is on.

one of the uvch's is not plugged in all the way

I would check the code if you can, and also agree prob a connector lose some place.

Thanks for all the help. It turns out the 9pin connector on the drivers side was slightly loose inside the valve cover. I was not even aware that the connection was there but it was obvious once I looked. All is back in good order.
