I am having trouble starting my 99 K2500 with 88,000 miles. Once it is warm, it fires right up. In the mornings, however, it takes more time to start than it used to. I figure it is time to replace the glow plugs.

I bought a new set, Delphi HDS309's, and I'm ready to go. I've searched the threads and found all kinds of great advice on replacing the plugs, but I'm still not comfortable. Here is what I have gleaned:

1. Spray them first with CRC or some other lubricant.
2. Remove all four on the driver's side, replace.
3. Begin efforts to remove passenger side plugs, stop. Wonder about engineers who put everything in the way. Promise to try again the next day.
4. Watch football instead. Resolve to do it next weekend.
5. Try again the following weekend. Quit. Start looking for GMC dealer still in business.
6. Start thread and ask for help.

How do I get out the four on the passenger side? Thank you in advance for any help. Also, what happened to the references for mechanics the site used to have? Is it gone for good?
