I agree completely, having done this job twice in the past month, although I had to be 
reminded how much easier it is to remove the injectors. First time, I did it the 
masochistic way, trying to reach the #1 & #2 with all means of little wires, 
screwdrivers, small wrenches and duct tape. (3 plugs were dead). A week later, I did 
it again, but my compression tester had arrived, so I pulled the lines and injectors. No 
contest. I can pull the lines and injectors in about the same time it takes to pull the #1 
glow plug. With the injectors out, trouble shooting is easy, and replacing plugs is a 

It's also a good time to check & replace the fuel return lines. I have two ends which 
came apart pulling them off, which means they might have failed soon, making a 
mess of fuel at the least convenient time. I always replace the lines "long" allowing 
for trimming 1/2" off each end when the ends get worn, since that is where they 
usually fail.
