directly behind the air filter is the controller for the glowplugs . It screws into the block and will have a couple of wires attached to it . It works of the water temp.. notorious for going bad . Simple solution is to add a pushbutton switch inside the cab .Run a wire that is hot all the time to one side of the switch and another wire from the other side of the switchto the glowplug relay located on the fenderwwell. Hook this wire to the small terminal on the relay that is closest to the engine .When you are ready to start the engine ,hold the pushbutton in for about 10 seconds which in turn will close the relay energizing the glowplugs. There should be 12 volts at the top of the glowplugs with this switch closed.[may need help as one person closes switch ,other checks voltage] If no voltage at glowplugs check the inline fuses[should be 2] on the wiring harness next to the relay,or check the glowplug wiring harness for a broken wire in the harness itself[ask me how I know like to have drove me batty]Also be sure all glow plugs are good and not burned out. If any are bad take a fools advice and DONOT replace rhem with the autolite Glowplugs,Go back with the Bosch plugs as the Autolite glowplugs will swell at their tips ,and then they are a pain in the rear to remove ,but that is another story.
