I can solve this problem for you but I need the right information. They have your truck listed as a 2003 F-350. Then it is also listed as a 2007 and want to know where the glow plug relay is. I need the correct year and model with the proper engine displacement.

    The 6.0L doesn't have a relay it has a glow plug module it is located on the passengers valve cover in the very front. It has 2- 9 pin connecters going to it. If you don't have a scan tool to test it then you will to check it one at a time. There are 4 wires per plug for the glow plugs. The 1 plug will have a white with a light green tracer, red with a light green tracer, dark green with a white tracer, and a red with a light blue tracer. You will have to get a clamp on amp meter and have someone cycle the key on and check one wire at a time. You must cycle the key check each one individually. Each one should pull approximatly 25 amps a piece. The other connector also has 4 wires in it for the other bank. The wires are pink with a light green, black with a pink tracer, dark blue with a white tracer, and a red wire. You can check these wires the same way as the other connector. The first thing I would do is make sure that the glow plugs are ok. All the wire colors I gave you are for the glow plugs. Take a test light and hook the ground side of the test light to the positve side of the battery. Then touch something on the engine to make sure that the test light works then take your light and check eack wire for the glow plugs individually. If any of them doesn't light the test light then something is wrong with that circuit so you will have to find out what it is it could be the wiring or the glow plug itself. Good luck any more help let me know.

1983 Chevy Silverado, Glow plug light will not come on, Truck will turn over but not start, fuse panel has no blown fuses, I suspect the Glow Plug Relat but I don't know how to verify it is bad.


With most relays, you have 4 wires. One is power to the component the relay controls, one is a ground to the relay magnet, one is power to the magnet, and the fourth goes to the component, in this case the glow plugs. The ground usually comes from the computer.
With the key on you should have power to two terminals and you would jumper the hot terminal to the glow plug terminal. Or use a test light or meter to check for power on the glow plug circuit.

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

Glow plugs flashing when engine is running


HI. This is an indication of a failing glow plug. It will be necessary to test each plug to isolate the issue, or run a diagnostic scan on the CPU. During the scan, you should be issued a code that will isolate the actual glow plug that is malfunctioning. If you insist on testing each plug, use my procedure below to assist. You can find the resistance specs in your operators manual.


A test light can be used to determine if the glow plugs are working.


1. With the test-light grounded, insert the test light probe into a glow-plug wire to check for continuity.

2. If the light comes on, check the other cylinders in the same manner. If the test light failed to light, check for continuity at the glow-plug relay.

3. If no power is present, check the control circuit of the glow plug relay.

4. If the control circuit is working, the relay may be defective (FYI, manufacturers may have the system fused and fusible links may be located throughout the system).

5. If the glow-plug circuit is working, the glow plugs themselves may be defective.

Checking glow-plug resistance:(Remove the plug for this test)

1. With an ohmmeter, connect one lead to the terminal and the other lead to the body.

2. Read the resistance and compare to specifications.

3. A visual inspection may also be necessary to check for excessive carbon buildup and physical damage to the tip.

4. A glow plug that has excessive carbon deposits on its tip can give the correct ohmmeter reading but still not work. Clean the tip with carbon cleaner.(DO NOT USE A BRUSH TIP CLEANER)

2004 audi a4 tdi not ticking over properly for first 15 seconds when cold , rev counter needle unsteady ?


Check up glow plugs (4 pieces) and glow plug relay placed inside left bottom area near clutch pedal. It is no.4 relay from left to right. Verify also all electrical cables. In most cases the glow plug relay is out of order.

Engine turns will not fire up glow plug sign flashing


HI. Usually, when this light illuminates, it will signal that one, or more of the glow plugs are malfunctioning. I recommend to test all glow plugs, so that you may isolate the defective plug.

glow plug relay should be on the front are rear of intake.you have a mechanical low pressure pump on the passenger side low near the front. or a electric low pressure pump on the starter side. your truck should have the low pressure electric pump. to check fuel pressure you disconnect the out let line to do a out put test.on the electric low pressure pump.put out let line in a container.crank engine for 20 to 30 sec.you should have a good flow of fuel no dribbles.if dribble replace low pressure electric pump.the mechanical low pressure pump out put test you disconnect fuel line from the fuel filter inlet line.disconnect wire at fuel injection pump electric shut off solenoid .place the fuel line in a container. crank engine for 20 sec. fuel flow looks good.pump is good .if dribbles.replace mechanical low pressure pump.to check glow plug relay you need a .diesel repair ford manual to show you where to put a test light to check the relay.WEAR SAFETY GLASSES WHEN WORKING ON DIESEL ENGINES.DONT DISCONNECT THE INJECTION PUMP LINES WHILE ENGINES IS RUNNING.THE FUEL PRESSURE IS SO HIGH SPRAY IN YOUR EYE CAN CAUSE BLINDNESS.GET IN SKIN OR SORE CAUSE BLOOD POISON. CAN ALSO CAUSE A FIRE BE VERY CAREFUL.
