Check Engine light=Glow plug issue

So the check engine light has been on in the truck for a month so I take it over to Auto Zone and they do a scan which says my that there is an "open" issue with the preheat, glowplug curcuit. I havent had a chance to look at it but you guys have been a major help in the past so I thought I'd ask the experts for their opinions before I open the hood. Thanks in advance!

Did they give you a code for the problem? Just to narrow it down to a better location of the problem.

After actually looking at the printout it states that the #2 Glow plug is faulty. I have never needed to preheat the truck but it looks like Im going to be spending some time & money on them anyway.

Well, if you have to replace the glow plugs, you may as well replace them all. I saw some on ebay that I liked and have been meaning to get, it's just that after 9 years and 245,000 miles, my glow plugs won't quit!

If I were you, I'd get some of these: Ford Powerstroke 7.3 Turbo Diesel Glow Plug Plugs:eBay Motors (item 160365690785 end time Oct-07-09 19:47:54 PDT)

I know the glow plug harnesses frequently become corroded which can throw a similar code. Might be worth checking out.

If you never had to preheat your truck, then I probabbly wouldn't worry about it that much. I guess its all about the wheather.
