newington is not a bad trip for me, i live near poughkeepsie NY.
the glowplugs well two methods i use the easy and the tried and true.
the easy method: put a amp meter on the wire going to the glowplugs, cycle the key so the glow plug light goes on and check the reading on the meter, they should draw aprox 60 amps.
the tried and true method i use. pull out all the injectors and turn the key on, look in the hole where the injectors were, you should see bright red glowplugs in all 4. caution only do this method on a cold engine.!
good luck and i will get to you soon about meeting up somewhare to take a look at your timing.
