Glow plugs
Easiest way to test glow plugs is by removing the cover of the pre-glow relay, unplugging the 6-pin connector, and measuring the resistance to ground of each pin. That checks both the glow plug and the wiring. Resistance should be less than 1 Ohm. Bad glow plugs will measure hundreds of Ohms or infinity. Even a cheap meter will work because you can compare the readings; a bad glow plug will stand out by having a reading different from the others.
Some of the glow plugs can be replaced by removing only the crossover; #6 is the worst, being buried under the manifold and behind the oil filter canister.
