Truck wont start, but only if you hear a click


I copied this from my GM service manual for 1982 6.2 diesel.

1. If the glow plug relay is not clicking on and off then turn the ignition to the RUN position and connect a 12V test light to ground and touch the pink/black wire in the glow plug relay connector.

2. If the light is off repair the open cicuit in the pink/black wire to the splice.If the light is on then touch the light blue at the glow plug relay connector.

3. If the light is off replace the glow plug relay. If the light is on, disconnect the connection at the thermal controller and touch the black wire in the connector.

4. If the light is off, repair the open circuit in the light blue wire from the thermal controller to the glow plug relay. If the light is on repair open circuit in black wire back to a splice. If no trouble is found replace the controller.



You should also get your hands on this Haynes book. Diesel Engine Repair Manual, part # 10330. Excellent coverage on the 6.2 and 6.5. In it, they say that early 82\'s have a hole at the number 2 hole on the pin connector of the wire harness for the thermal controller. this allows dirt in there and corrodes the pins. Remove the connector and clean thoroughly the pin area on the connection and controller. Seal the hole with some silicone. If things are still acting up, replace the wire harness connector.



Hope some of this helps.

A commonrail diesel ford ranger won't start,but it crank


You would need to check the glow plug timer circuit and the fuel supply. Diesel glow plugs can wear out. Make sure the "Ready light" is working and that you hear the timer cycling. Usually the lights will dim as the power goes to the glow plugs.

The glow plug wire can be checked with a Voltmeter inserted on a wire from the Relay timer. The glow plugs are tested when they are removed from the engine. If you get this far, you can use battery cables to test them. They can melt. Ask for more details about proper procedure.

Citroen relay van 2.0L HDI


Have a load test done on the battery as the glo-plugs should get very hot very quickly. Diesel engines have to have a high rpm crank speed or they will not start and will leave unburnt fuel in the cylinders ( wet glo- plugs). Every indication is that the battery is flat or is not the right capacity for the car.

2003 f250 6.0diesel will not start has fuel at fuel filterwill try to run on starting fluidwith interminent spray


fuel at fuel filter doesnt mean its getting the correct pressure to operate the injectors. do not spray starting fluid into a diesel motor, you will damage the rings, score cylinder walls, burn valve guides... etc . starting fluid is not designed for diesel engines. the only way to test the fuel system is to test it by hooking up a pressure test gauge to the service port. the next most likely issue would be a faulty glow plug relay or 1 or 2 faulty glow plugs.

7.3 Liter Diesel starts hard in morning, ok if not left more than 8 hours. How to check the Glow Plugs?


Your glow plug relay is located on the top of the engine on the right side toward the front. Some models there are 2 solenoids. A large one toward the front and a smaller one right behind it. The glow plug relay is the smaller one toward the rear. The larger front one is the intkae heater relay. To test the glow plug relay turn engine to on. dont start it. both of the large terminals should have power with key on. then turn engine off. only one large terminal should have power. If when you turn engine to on you only have power on one side then go to this test. Turn engine on and test smaller wire. it should have power. If it does replace the relay. If the smaller wire does not have power you have an ignition problem or power (wiring) problem to the relay. Also note the engine needs to be cold. If temp of engine is over 130 the computer will not turn the glow plug circut on! Most of th time this is what fails and not your glow plugs.

Jaguar x type 2 litre diesel. how often should the glow plugs be changed?


Hi, glow plugs does not need changing unless the vehicle struggles to start in the morning or when cold. When testing the glow plugs, they should not take longer then about 5 seconds to become red hot.

1997 VW JETTA DIESEL GLOW PLUGS


The glow plug relay is responsible for the duration of glow plugs, this needs to be the starting point. You should get a 12v out for so many seconds when ignition is switched on.
I have taken the cover off relays in the past, cleaned up the internals, sprayed with circuit cleaner and got plenty more years out of them, worth a try.
