SOURCE: 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.

Cheers

SOURCE: No voltage too Glow Plugs.

These are spark plugs you are talking about right? Glow plugs are in diesels. If it is no voltage to spark plugs, do a test on your plug wires.

SOURCE: How do i replace my VW SHARAN 02 glow plug relay.

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

The glow plug controller has the ability to perform internal checks, an open or a short to ground on each of the glow plug circuits. If the glow plug controller senses a problem in a glow plug circuit, the glow plug on the affected cylinder will be disabled and the glow plug controller will send an error message to the engine control module (ECM). If this condition exists, the DTC will set.
Conditions for Setting the DTC
The glow plug controller detects that the glow plug control circuit is open, shorted to ground, or has more than 1 ohm of resistance.

Circuit/System Verification
Verify that DTC P064C is not set.
If DTC P064C is set, refer to DTC P064C.
Ignition ON, engine OFF, observe the scan tool Glow Plug 1-Glow Plug 8 parameters. All 8 Glow Plug parameters should closely match each other.
Refer to Testing for Intermittent Conditions and Poor Connections if you cannot duplicate the conditions.
Engine running, observe the DTC information with a scan tool. DTCs P0671-P0678 should not set.
Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.

DTC C0035 Left Front Wheel Speed Sensor Circuit
DTC C0201 Antilock Brake System (ABS) Enable Relay Contact Circuit
The system relay, located within the electronic brake control module (EBCM), supplies battery voltage to all of the valve solenoids and to the ABS pump motor. When the relay contacts close, the EBCM monitors the voltage supplied to the valve solenoids and compares this voltage to monitored ignition voltage.

Glow plug troubleshooting


Connect a volt meter to earth and glow plug supply wire, turn ignition on, should get a battery voltage reading for about 10 seconds, if not the timer relay is not supplying power. If you get voltage, remove the glow plugs and test with an ohm meter for resistance, (no reading? open circuit, not working). Heater relay is a heavy duty relay with a 60amp battery supply, generally in the bulk head area. (DON'T DIRECT FEED THE GLOW PLUG! could burn them out)

PO380 and p1316 what do thies coads mean.


P0380 - Glow Plug/Heater Circuit "A" Malfunction
Bad glow plug. The glow plug system is used to assist in providing the heat required to begin combustion during cold engine temperatures. The glow plugs are heated before and during cranking, as well as initial engine operation. The engine control module (ECM) controls the glow plug ON times by monitoring coolant temperature and glow plug voltage. The California Glow Plug system has eight individual glow plug supply circuits between the controller and the glow plugs. If the feedback voltage from the controller to the ECM is not within range, DTC P0380 will set.

- The glow plugs are commanded OFF and the glow plug feedback is more than 2 volts. or
- The glow plugs are commanded on and the glow plug feedback is not between 5 volts and 6.2 volts.

Keep in mind that the "wait to start" light only comes on while the voltage is dropping in that circuit. This should only take 3-5 sec's. If it takes longer, refer to your "Likely problem" you listed above. That would be the Heater Module. If your glo plugs stay on, your batteries would be dead in no time. If any of your plugs go bad, they would each be listed on the reader per cyl 1-8. If you need to change the Module,


P1316 - Injector Circuit / IDM Codes Detected.
This code indicates that codes are stored in the IDM

Possible causes are as follows:
- Injector(s) or circuit(s)
- Open or shorted IDM enable circuit
- Open/short in EF circuit
- Open/short in FDCS circuit
- IDM relay
- IDM powering circuits
- Failed IDM
- Failed PCM

Check your Injector Driver Module wires, circuits 821 (Brown/Orange) and 818 (Grey/White) between the PCM and IDM. On the IDM side, the connector pin numbers are 17 for circuit 821, and pin 4 for circuit 818. You should check for high resistance in that circuit, short to ground, or open circuits. If wiring checks out good, you may need to replace your IDM. It's not uncommon for water intrusion into the module, due to its mounting location. Also check the engine wiring harness where it routes up over the driver side shock and/or driver side valve cover. That code is either a key-on/engine-off or a continuous memory code.


Hope this helps (remember to rate this answer).

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)

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.

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.
