If you can plug it in to the connector it will work most of these relays are the same you can test them by interchanging them as long as it fits correctly

Posted on Dec 03, 2016

Testimonial: "Hello there, many thanks John for your prompt reply regarding the differences of type numbers on the two glow plug control relays. The first number is the number of the unit already installed in my Astra vehicle, and the 2nd number is the number on the other unit that was given to me by a mechanic friend of a friend. These units are physically identical apart from the serial numbers. The problem I was experiencing with my vehicle was that on the cold and frosty morning the vehicle would only start if I turned the ignition on and off repeatedly for about 10 times. It would then issue dense smoke from the exhaust before running normally. This morning was a light frost, I changed the units, turned on the ignition, waited approximately 8 seconds and then the engine started immediately. I am now waiting for a heavy frosty morning and hopeful that my starting problems will no longer exist. Again, thank you for your prompt and helpful information... Peter"

Relays are black(5 pin) or grey(4 pin) At least for GM. If you are going from a big one to small one, or vise versa. it works. Most panels now days are fitted for 5 pin relays. Meaning that you can use a 5 pin in place of a 4 pin. You just can't use a 4 pin in place of a 5 pin.

    Always best to use what the car manufacturer installed, unless there's an upgrade / update for your vehicle.

  • Randy Ohler Dec 04, 2016

    Just a simple relay. No difference between the big ones and the small ones. Except for the size.

The amount of current sometimes is determined by relay and what your vehicle has.

Why is my ford diesel hard to start


Hard starts, can be a number of different things... But most common is some or most of your glow plugs are bad, or your glow plug relay.
if you have not changed to glow plugs, in a few years, you should just replace them. They're not that expensive.
when glow plugs, and the relay are working properly, vehicle starts right up.

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.

Starting issue, I have a 1993 ford f250 7.3l pre powerstroke. I started the motor and it stalled out like there was a short, now when i turn the key my glow plugs do not fire and wait to start doesnt show...


On some Models the glow plug Relay does not have an integrated Power Relay. This means there is a second Relay before the glow plug Relay that feeds it power.

You should check the wires running to the glow plug Relay for power with the key ON. Check some other wires off of the Ignition switch to make sure your 20 year old Ignition switch is good.

There are some sites which show vehicle wiring. Autozone has a free section after Registering your vehicle but it takes a little sorting through the Help section. There should be a fuse to protect the above Relays.

Make sure you find the Diesel-equipped wiring circuit. Diesel ignitions are different from gas units.

Landcruiser 05 1HZ, Glow Plug Light comes on when I decelerate and goes off when I accelerate again - any idea


Hello kbmind, A number of different glow plug systems were used on the Landcruiser, depending where it was made and what country it was shipped to. However, they all serve the same purpose on a diesel injection. To preheat the combustion chambers. If your light is on when you deaccelerate the control module thinks the cylinder is cooling down & fires up the glow plug. This usually indicates the glow plug relay is weak and/or the glow plugs themself are worn.
Depending on your mileage, i would say it's the relay. The glow plugs can be tested with an ohm meter to determine if they need to be replaced. I hope this helps.

I have a vw bora 1.9 tdi and the heater plug light has started flashing and the car says engine workshop


There are a number of different causes of this problem. Check all glow plugs. Check glow plug relay. If both are ok....This may seem unusual...Check the brake light switch situated at brake pedal. A faulty brake light switch will cause the glow plug light to flash
Good luck with it

I have a 1997 ford F350 WITH A 7.3L DIESEL, it turns over but will not start. My wail to start light or other indicator lights do not come on when I turn on the key.


The first thing to do is locate the owner manual.

Look for the glow plug relay MAIN FUSE location.

The glow plug portion of your van is not working.

This difficulty scale from 1 to 10 is a 9.

You will need a DVM and tool undo the cables to each glow plugs.

It's a 1 to 2 hours troubleshooting job.

I'm going to fire off a quick list

====
Check / replace blown glow plug relay main fuse
====

Disconnect each center nut of the glow plug wire. PLEASE CHECK ONE AT A TIME.

Read the resistance between the center of the glow plug and the metal base of the plug.

Please take good note on each glow plug resistance reading.

MAKE SURE all cables are put back and tighten properly.

Compare the resistance on all cylinders.

OPEN/high resistance is bad glow plug.

In general 3 ohm or less is OK.

You should buy one and use its value as baseline.

===

Glow plug relay can be bad.

You will need the VOM and a friend to turn the key.

Check the voltage to each glow plugs. It should be 12.6-13.6 volt.

Be careful,the plugs will get HOT.

Compare the voltage on each cylinders.

====
So the problem can be combination of

glow plug relay

glow plug relay main fuse

glow plugs

ignition switch is unlikely but I'm going to list it anyway.

Once again,this is a difficult and time consuming job. I will ask a friend to help out,

Good luck.

Glow plugs causing starting problem


if you need connectors and terminals for the glow plug connections under the valve cover, Ford sells then so you don't need a whole $600 harness.

info for your use

Section 03-07B: Glow Plug System 1996 F-250, F-350, F-Super Duty Equipped with 7.3L Diesel Engines Workshop Manual
DESCRIPTION AND OPERATION Glow Plug System The 7.3L diesel engine uses a glow plug system which preheats air in the combustion chamber to improve cold engine starting. The system consists of eight glow plugs, the glow plug control module (12B533), powertrain control module (PCM) (12A650), engine oil temperature (EOT) sensor and barometric pressure sensor (BARO sensor) (12A644). The glow plug system is electronically controlled by the powertrain control module. The powertrain control module energizes the glow plugs immediately after the key is placed in the ON position and then determines how long the glow plugs will be on according to the engine oil temperature and the barometric pressure. The required time for the glow plugs to be energized decreases as the engine oil temperature and barometric pressure increase. The glow plugs are self-regulating, and the powertrain control module controls relay ON time. The powertrain control module protects the glow plugs by energizing them for short durations if the battery voltage is abnormally high.

Possible Causes: Insufficient glow plug ON time will not allow enough heat to accumulate in the combustion chamber to easily facilitate starting. If the glow plug system ON time does not meet any of the specifications in the accompanying chart the problem is most likely a faulty wire harness connection, ground connections or glow plug relay.

If the glow plug resistance to ground is high, the most likely causes are an open UVC (under valve cover) harness or open glow plug.
--------------------------------------------------------
Relay Operation
Install a DVOM on the glow plug feed side of the glow plug relay (large stud with two wires connected). Turn the ignition key to the ON position but do not attempt to start. Note the time in seconds from when the key is turned on and the glow plug relay energizes until the glow plug relay de-energizes. The glow plug relay makes a loud click noise which is easily heard when it energizes and de-energizes. The dome light will dim and the dash voltmeter will dip when the glow plugs are drawing current from the battery. Compare the times measured to the table (time will be affected by engine temperature, battery condition and vehicle altitude). The voltage at the glow plug feed terminal may vary from 9 to 12 volts depending upon battery condition.
--------------------------------------

-----
If battery voltage not present check for B+ at power supply terminal (terminal with single large wire). Power for glow plug power supply is supplied from starter relay through two fusible links at solenoid.
Glow Plug Operation
Disconnect all of the glow plug/injector harness connectors from the valve cover gaskets. With the pigtail installed, measure glow plug resistance to ground (preferably B-). A resistance measurement of .1 to 6 ohms indicates a good glow plug.



Glow Plug Harness Continuity
Measure for continuity from the connector harness to the glow plug feed terminal on the glow plug relay. Resistance should be less than 5 ohms.
Incorrect measurements will result if all glow plug/injector connectors to valve cover are not disconnected.

---------------------------------------------------
Glow Plug Relay The glow plug relay (12A343) has a plastic base and two mounting bolts. It is operated by the powertrain control module (PCM) (12A650) which senses engine oil temperature, PCM voltage and barometric pressure. When the engine oil temperature or the barometric pressure is low, the PCM activates the glow plug relay and the glow plugs. If the PCM voltage is too high, the powertrain control module deactivates the glow plug relay and the glow plugs immediately energize for a shorter duration, decreasing the modulation of the duty cycle.
-----------------------------------------------
Glow Plug Removal
  1. stj~us~en~file=ani_caut.gif~gen~ref.gif WARNING: THE RED-STRIPED WIRING HARNESS CARRIES 115V DC. SEVERE ELECTRICAL SHOCK MAY BE RECEIVED. DO NOT PIERCE.
    Remove valve cover (6582). Refer to Section 03-01D .
  1. Disconnect glow plug electrical connector using a pair of pliers.
  1. Remove glow plug using 10mm socket.
  1. Clean and inspect glow plug tip for damage. Replace if damaged.
Installation
  1. Install glow plug and tighten to 19 Nm (14 lb-ft).
  1. Connect glow plug electrical connector. Make sure glow plug wiring is routed to avoid moving parts.
--------------------------------------------------------------
Glow Plug Control Glow plugs are used to warm the cylinders to improve cold-engine starting. The PCM uses the engine oil temperature (EOT) sensor and barometric pressure (BARO) sensor to determine how long the glow plugs will be on. The PCM energizes the glow plugs longer if the engine is very cold or if the barometric pressure is low at high altitudes.
The PCM controls the relay that supplies power to the glow plugs with the glow plug control (GPC) signal. When the GPC signal is grounded by the PCM the relay closes, turning the glow plugs on.
The glow plugs are controlled by the following sequence:
  1. PCM energizes the glow plugs.
  1. The PCM energizes the glow plugs immediately after the ignition is placed in the ON position.
  1. The PCM then determines how long glow plugs will be on based on EOT sensor and the BARO sensor. The required time to warm up the cylinder decreases the engine oil temperature and barometric pressure increases at low altitudes.
Glow Plug Lamp Control The glow plug lamp (GPL) signal controls the WAIT TO START light located on the instrument panel. This light is used to indicate when to start the engine. The cylinders are being warmed by the glow plugs during and after this light is lit. The PCM energizes the glow plug lamp longer if the engine is very cold or if the barometric pressure is low.
When the GPL signal is brought low, the "Wait to Start" lamp is turned on.
The glow plug lamp is controlled by the following sequence:
  1. PCM lights the WAIT TO START light after a key on reset occurs.
The PCM determines the glow plug lamp activation time based on engine oil temperature, barometric pressure and battery voltage.
  1. PCM turns off the WAIT TO START light.
The glow plug lamp is turned off when the timer counts to the number of seconds specified by the PCM. The glow plugs will normally remain on longer than the "Wait to Start" lamp.

Glow PLugs and Relays


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.
