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.
The glow plug controller or power solenoid has likely failed. The solenoid is located on the driver's side inner fender. If the solenoid tests ok with the key in run, then replace the glow plug controller.
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.
