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

SOURCE: glow plug relay reading 0 with ohm meter. changed

Pick up a copy of Haynes Diesel Repair Manual, part # 10330. It has an extensive diagnostic and repair section for glow plugs in your truck, either 6.0 or 7.3. It's only $20 and well worth it. It has diagrams and wiring especially pins on the plug-ins. You should be able to get it at the auto parts store. Hope this helps.

Wiring diagrams


Check for power at glow plug, connect meter to earth and wire feed to plug, should get a 12v feed, if you get a feed the plug is duff. You can remove the plug and test for an Ohm's resistance, no resistance it's broken! If you have a power supply then it is possible the glow plug relay is not working. Follow the cable from the glow plugs, this is generally a thick 30/60 amp cable, the relay is larger than other relays and not in the fuse box, possibly on the bulkhead or inner wing because of the power it has to transfer. DO NOT DIRECT POWER FEED THE GLOW PLUGS, You can burn them out!

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.

I have a 2003 gmc sierra duramax diesel and im in need of a glow plug diagram?


The diagram is simple each glow plug is connected in a series circuit like this -0-0-0-0-0-0-0 that's a in-line 6 for a V-8 it would look like this
[-0-0-0-0
[-0-0-0-0
and the plugs would be hooked up on the back then if you follow the wire to the glow plug relay you will find that the relay has four wires one to battery one to the glow plugs one to the ignition switch and one to ground in the box. If you want you can purchase a manual for 5.99 on-line. and it covers the three fuse-able links for this system and the new Glow plugs available for this truck here is the web page. http://www.wiring-diagram.com/?gclid=CMuAvJ3Ql58CFQZfagod0jpAxQ

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


glow plug wire harness under valve covers often deteriorates causing no glow plug heating. The connectors and wire terminals are available from Ford as a kit or individually. Do not replace the harness. $600!
Still need the fuse panel circuit? Look in owner manual.
glow plugs use a relay too.
