[Vwdiesel] 92 ECO injectors

[TexasTDI]

How can you tell the difference between failing injectors and failing glow
plugs?  I think I have one or the other, or maybe even both.  Not too
mention MAF problems as well.

I'm currently running with the MAF unplugged until the new one comes in.
But now in the morning, when the engine has been sitting for at least 8
hours overnight and is cold, it starts but does so sluggishly.  Idling very
rough until I step on the accelerator.  Then a nice cloud of white smoke
appears.  After a few minutes, when the car has warmed up, it idles fine.

This past winter (2003) I would sometimes have to cycle the GP's two or
three times for the car to start.  Didn't have to do that during the prior
winter (2002).  Also, I'm noticing a very distinct noise near the fuel pump.
A loud clatter over and above the normal diesel clatter.  It's hard to
pinpoint the exact location.  But it's definitely coming from the top of the
engine, on the passenger side, near the fuel pump and timing belt.

Failing GP's ?

Failing injector(s) ?

Failing fuel pump ?
