You can test each glow plug while still installed in the engine. Just get a test light and connect it to the positive terminal of the battery and touch the point of the test light to each glow plug terminal. If the light lights up the glow plug is good if not it is bad. You can replace the one or more that are bad or replace them all since they may not be too far behind.

Is there a test to see which glow plugs may not be working?
This test will determine what glow plugs are working. ( It will not determine a partially burnt plug ). Disconnect the glow plug wires at the plugs .( You must unplug all of them for this test to work ) Connect a test light to the positive terminal of the battery. Touch the electrical connector at the end of the glow plug with the test light. If the light goes on the glow plug is working. Make sure you touch only the electrical connector on the plug. If you touch any other part (metal) of the plug the test light will light giving you a false reading.

The best way that I have found to test the glow plugs on anything is with a simple ohm meter.

You should have a tolerance to be between. If you Are not there, odds are its bad

You have a problem in the glow plug system. You will need to test for a shorted glow plug by making a test harness with a 15 amp fuse in it and applying 12 volts to each glow plug to see which blows the fuse. You will also have to replace the glow plug module/relay which is loacted under the battery shelf under the hood. Be very careful when trying to remove the glow plugs. Only attempt with a fully warm engine ( drive it for 30 minutes first ). Do not try to force them to turn, they will break.You have a problem in the glow plug system.
