As to the tensioner, the aluminum rocker has a bearing in there. Make sure that ir moves freely without the shock and spring on it. Also make sure the pully spins freely. There is a diagram in the manual in your glove box that shows you how to route the belt, double check that. If all else fails replace the spring they are cheap, see where that gets you.

In reading more on DieselGiant.com, it looks like the GP test procedure would be the same with the exception of testing the strip fuse since it is obviously absent. If one were to test each plug, it seems that it would be possible to find the bad one - OR if all plugs seem to be fine, then the problem would be with the relay itself. My mechanic has already determined that the power TO the relay is fine - it's the power from the relay to the plugs that is down. Apparently, these relays have an internal circuit breaker that will reset when it no longer detects a problem. So, the task at hand is to determine if I have a defective GP (or multiples) that is setting off that circuit breaker, or if the relay itself is the problem. Unfortunately, my mechanic has already ordered the new relay with the plan to install it - it may be installed already, I just don't know. I don't know if he knows about checking each of the glow plugs. Arrghh... if he cannot get to the bottom of it today, then I will have it towed somewhere else Monday morning. This mechanic is a good friend and he really wants to help, so I truly hope he can find the problem - he takes pride in his work, so I hope this one doesn't stump him!
