Here is the problem, the truck cranks up fine cold or warm; the problem is it takes about 8 minutes to get the truck good and warm before I can actually start driving it. While it’s getting warm it has that almost gonna die out loopy kind of engine movement. If I start driving it before the proper warm up time the beast is rough on idle and lots of cool blue smoke comes out the pipe and some times when I give it gas there is no acceleration at all. But if I wait the 7 to 8 minutes to allow it to warm up. She hums like a beauty. I have about 94K on her. I know over the summer (03) I may have cranked her one to many times before the "wait to start" light went off. Any suggestions out there about where to start trouble shooting?

It sounds like you have 1 or more bad glow plugs. The glowplugs, when working properly, are heating the intake to a point where cobustion is cleaner. The blue smoke is unburned fuel. You might check the relays and acertain that they (the glow plugs) are getting power. With the glowplugs drawing power from the alternator on an intermittant basis, one can notice a drop on the guage intermittantly for those first 7 or 8 minutes. This is normal and should be noticeable if the glowplugs are funtioning normally. They draw so much power that one can often hear the change in idle from the alternator being taxed off and on.
