Good Day
The glow plug relays are located on the right front shock tower. Remove the cover and you will see two relays If I remember I think they are round, but not sure.

Please let me know how you make out and if there is anything else that I might be able to help you with.

Cheers

Your glow plugs are going bad and need to be replaced. This is a sign to you that they are basically running all the time because they dont know that thye are heated up and the car is running. Common problem with diesels

SOURCE: Jaguar glow plug problem

The Glow plug coming on, and the car going into limp home mode, is a default safety feature that occurs when the engine management system picks up any kind error message from the many sensors now used on the car.
I've found the glow plug light problem with my Jag, it was the air filter. Apparently Jaguar servicing change it every 3rd service (not a good idea). I changed mine, it is a new car. I had the EPR valve cleaned and a major diagnostic carried out by a local garage (who had the Jag diagnostic software). It turns out I also need a new Turbo; the actuator is sticking (£759.00 plus 3 hours labour). But hey, the main limp home mode problem is fixed and I can drive my Jag confident it will accelerate when press the gas.

You have to replace the defective glow plug. You can test the glow plug without the test light. Just put a wire on the bolted end of the glow plug and connect this to the battery (+) terminal. Then, put a wire around the body of the glow plug and connect this to the battery (-) negative terminal. Hold at this position for a minute or less. Good glow plug will heat up.

As far as the wiring schematics, I will just describe
it. Your ignition switch is connected to the positive
terminal of the battery by way of the fuse in the fuse
box. From the switch it goes to a timing relay before
going to the glow plug terminals. The glow plug body
is screw mounted to the engine block which serves
as the negative terminal. So, as you switch your
ignition, it heats up the glow plug enough to give a
combustion of the atomized fuel in the cylinder piston
of your car causing it to run.

SOURCE: peugeot partner wopnt start replaced glow plug

what voltage u getting ?. did it just stop and then not restart. if its getting fuel and glow plugs are working the next two items id look at is the cam shaft and crank shaft position sencors. also make sure ur battery is in good condition, so starter motor is turning fast enough to build up the correct pressure on the rail.

Rodeo isuzu c190 1981 model ,,no heat on theglow plugs very dificult to start


HI Theo, It is not always a good idea to connect the glow plugs directly to the battery. Did you read the operating voltage of those you fitted. Twelve volt systems, very often use anything from nine volt to eleven volt, but very rarely twelve volt. I suggest that you test each of the glow plugs and replace those which have burned out. I'm fairly sure that when you noticed the problem it became evident with hard starting. That was probably when the first failed. It is very possible that you also have a problem with the glow plug timing circuit in addition to the plugs. Make sure your vehicle is getting a voltage supply when the ignition is first turned on and that it is being fed to the bus bar or connecting cables which join the glow plugs in parallel. If the voltage is correct, I believe that will confirm blown plugs. Regards John

Getting a P1391 error code on my 01 Caravan, Changed PCM Sensors, wires, plugs, EGR, Whats Next? Please


P1391 Glow Plug Circuit Low Input (Bank #1)
  • DTC P1391 or P1393 will set when the monitor indicates that all four glow plugs are not being powered on that bank. An open in the glow plug circuits, glow plug relay, glow plugs or monitoring circuit could be the possible causes.

    Both DTCs P1391 and P1393 together will set when the monitor indicates that all eight glow plugs are not being powered. An open in all glow plug circuits, the glow plug relay, glow plugs, fusible links or all three monitoring circuits could be the possible causes.
  • Possible causes:
    • glow plug relay
    • glow plug shunt
    • open in glow plug circuit(s) or monitoring circuit(s)
    • glow plugs
    • PCM

Isuzu trooper hard to start


  • Even though the glow plug goes out it does not mean the all the glow plugs are working,
  • Remove glow plugs.
  • With a set of jump leads connected to a battery connect the earth lead to the body of the glow plug and touch the top of the glow plug where the wire is connected with the pos lead the top of the glow plug should heat up and turn red.
  • Only replace the ones that do not heat up.
  • Hope that helps.

I have a 1998 isuzu trooper 3.1td. The glow plug light on tha dashboard stays on for as much as 10 minutes sometimes. The local garage has tried to fix this with no success. Any ideas? Can I wire in a push...


If the glow plugs are faulty,this would be the reason for the problem,they are not glowing very well,unless the glow plugs have been replaced,then the circuit from the glow plug relay is faulty,or the relay itself,

How do i replace my VW SHARAN 02 glow plug relay. and what is it. i have been told that the glow plug relay is going. Could you please tell me what a glow plug relay is and what it does??? Also do i need...


the glow plug relay is a little black box normally located in the fues box, the relay regulates power to the glow plugs, if the relay is not functioning correctly the plugs will not heat enough or, you will have to allow a longer time to let them heat up, it acts like a switch as such, when you turn on your ignition it switches over to make a contact inside, which inturn starts the heating prosess of the glow plugs when they are at the correct tempreture or the onbored computer detects they are it then switches back , without it , say just using a fuse instead, your glowplugs will just get hotter and hotter till they melted, and no you dont have to change the glow plugs hope this helps, ime not good at explaining stuff in writing lol
