Technical Help..!!!
1 Disconnect the battery negative terminal.
2 Remove the air inlet ducting from the front of the engine.
3 Unscrew the nut from the relevant glow plug terminal(s), and recover the washer(s). Note that the main supply cable is connected to number 4 cylinder glow plug and an interconnecting strip is fitted between the 4 glow plugs.
5 Unscrew the glow plug(s) and remove from cylinder head
6 Inspect each glow plug for physical damage. Burnt or eroded glow plug tips can be caused by a bad injector spray pattern. Have the injectors checked if this sort of damage is found
7 If the glow plugs are in good physical condition test them electrically using a 12v test lamp or continuity tester
8 The glow plugs can be energized by applying 12v to them to verify that they heat up evenly in the required time.
a) Support glow plug by carefully clamping it in a vice or self-locking pliers. Remember it will become red hot
b) Make sure that the power supply or test lead incorporates a fuse or overload trip to protect from a short circuit.
c) After testing, allow glow plug to cool for several minutes before attempting to handle.
p A glow plug in good condition will start to glow red at the tip after drawing current for 5 seconds or so. Any plug that takes much longer to start glowing , or witch starts in the middle instead of the tip is defective.
10 Refit by reversing the removal operations.
All the above is from the haynes manual
