SOURCE: glow plugs wont turn on

They make two relays that will fit but only one will work. Call 772 283-8999 ask for John, He will tell you more than you really want to know, the dude is about the best diesel mechanic I know. You can email him at disinc@fdn.com. Tell him Peppi told you to contact him. If John is not available ask for Ron, he is better at GMC products ( no one is perfect ) but he can help you as well. They are real good guys and will take the time to help and can get parts for anything. Hope this helps

SOURCE: put new glow plugs in ran fine for 1 day now it wont start..

You may want to surf around on some of the powerstroke forums for detailed answers, but I know the powerstrokes use oil pressure to control the injectors so you may have some problems with the high pressure oil pump.
Again, it is just a guess. I just wanted to point you to some of the Ford Powerstroke forums which may be of much more help for you.
Good luck..

SOURCE: i have change the glow plug relay its brand new bt

The operatoin of the glow plugs heat up the combuston chamber before turning over the engine. ONce the fuel hits the combustoin chamber , The fuel will ignite.

The diesel engine only runs on air and fuel .

The glow plugs are basically a resistor that heats up the combustion chamber or pre combustion chamber.

So if the glow plugs are getting power now that the relay is change out , Yes the glow plugs have a major roll in starting the engne.

I hope this was helpful

Tip

Diesel has trouble starting


hi, if you have any problems starting any type of diesel engine then this is a very good indication that one or more of the glow plugs need replacing, to get you home you can try turning the ignition on and then wait for the glow plug light to go off then instead of trying to start the engine turn it off then back on again, doing this usually gets it started just to get you home but this wont allways work.

Its best you replace glow plugs sooner rather than later as it could leave you stuck without a vehicle.

To change the glow plugs follow these quick instructions.
1. Look where the injectors go into the cylinder head then just under these you will see a smaller plug that will have a fixed wire this wire will be running from glow plug to glow plug this wire is held onto the glow plug by an 8m nut undo this nut on top of all the glow plugs, once undone you will notice that one of the glow plugs has two wires the other wire is the wire that carries the power to all the glow plugs so just remember witch glow plug this goes to.
2. now once you have removed the connecting power wire remember witch way it runs so as to get it back on the right way round it doesnt matter to much but might be a bit tight if you put it on the wrong way round.
3. Now how to undo and remove the glow plugs: To remove you will need a deep 10m socket place this over the top of the glow plug push down to ensure tight fit then undo this glow plug will then pull out (make sure their is no muck around the glow plug that can fall inside the cylinder so just check)
once you have it out its best you replace all the glow plugs as once one goes you will find that the others wont be to far behind.
4. Fitting new glow plugs. When your fitting the new glow plugs put them into their hole and gently screw in by hand to make sure you dont cross thread the thread as this can be a nightmare to put right. tighten the glow plugs in as much as you can by hand then nip them up using 10m socket and extension bar now dont over tighten them as this will damage the thread just tighten up till just after they stop then you should find they are ok.
Refit the wire loom on top of all the glow plugs remembering to fit the main power wire to the first plug make sure you tighten the nuts up properly on top holding the wire in place.
Once you have done this you are now ready to start your vehicle you should now find it starts with no problems.

If you still have problems starting you need to now start looking at things like the diesel filter or even the diesel pump, ill explain about these in my next post ok

Jeep Cherokee TD LTD won't start, has new glow plugs; starter motor and new ignition; It started when first done, but now it's cold it won't fire up what else can it be?


wow, no year, nor country car was sold. wow.!
lots really.
but i cant do my testing,with my tools.
did you scan it yet?
the glow plugs dont work all by them selves they need power to do that. ( controller) I have this ammeter, i clam on the glow plug wires. and see heater current , if zero then the plug is open or
the controller is malfing.
i presume the car starts warm and runs all day .... but all I have is one word :cold to assume that....
does engine start with diesel starter spray.?
Yes/no
if yes, then the glow plugs are the issue,
if not , its fueling issues.
why not scan it first. and not waste time and cash on good parts.


what does
and new ignition? mean?
the key switch?

Quick check is to take a fairly thick cable from the positive terminal of the battery and touch it onto the glow plug connector , it should give a healthy spark as it makes the connection , no spark no glow plug

You need to check the glow plug system. Check for power from the glow plug relay.
