I could be quite a few things. Poor compression, injectors not quite
working right, timing off a bit, or, yes, even glow plugs.
And it could be starters, grounds, battery connections and even
Your best bet is to eliminate each one.
Since it's a 82, one place I would start is with the glow plugs. You can
mess with the strap, or if you can get access to a DC current probe,
you can meaure the current going to the group of four plugs.
Depending upon the plugs, expect 35 to 60 amps when glowing.
You'll need a hall effect current meter, and a friend to flip the
switch while you test.
