1992 Ford F350 7.3 Diesel, put in new glow plug controller, controller clicks off and on, but no power to glow plugs. What could cause this?


Hi Margaret , Does the glow plug wait to start indicator light on the dash come on ? And then go off after a couple of min. ? Check fuse K 20 amp in the under hood fuse box .This is one of three B+ power supplies to the glow plug control module > Two fusible link's are also B+ power supplies to the module . There is a 10 amp fuse located in the inside fuse box , fuse # 17 , this is power for the indicator light !

DTC P0671: Cylinder #1 Glow Plug Control Circuit
DTC P0672: Cylinder #2 Glow Plug Control Circuit
DTC P0673: Cylinder #3 Glow Plug Control Circuit
DTC P0674: Cylinder #4 Glow Plug Control Circuit
DTC P0675: Cylinder #5 Glow Plug Control Circuit
DTC P0676: Cylinder #6 Glow Plug Control Circuit
DTC P0677: Cylinder #7 Glow Plug Control Circuit
DTC P0678: Cylinder #8 Glow Plug Control Circuit

Circuit/System Description
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.

99 FordF250 Code p1391 & p1393


Hello
Here are the meanings of these codes.
P1391 FORD - Glow Plug Circuit Low Input Bank #1
P1393 FORD - Glow Plug Circuit Low Input Bank #2
I think you most likely have a burnt out Glow pug controller. Whenever this controller is replaced all glow plugs should be tested for proper function.

Check and make sure your glow plug controller is putting out voltage to your glow plugs, make sure voltage to your glow plugs is cycling. if it is not, at the front of the engine there is a temperature switch, if this switch is not working your glow plug controller will not work. also make sure you are getting diesel to your injector pump, if you are not, there is a high pressure switch at the back of the engine right behind the glow plug controller, if this switch is not working, your injector pump will not get fuel. also make sure both batteries are fulley charged, if one is low, your diesel will never start. you can jump out these switches, if your truck starts after bypassing, just make sure to replace them. i have a 1993 silverado C3500HD 2WD. good luck!

The engine light went on so I check it with diagnostic and and gave me the code P0380 Gold plug/heater Circuit A.


CODE PO380 GLOW PLUGS CIRCUIT A MALFUNCTION. POSSIBLE CAUSES. GLOW PLUG RELAY CONTROL CIRCUIT IS OPEN SHORTED TO POWER OR GROUND CIRCUIT IS OPEN, GLOW PLUG RELAY IS STUCK IN POSITION CAUSING CONSTANT POWER, GLOW PLUG RELAY IS DAMAGED OR HAS FAILED, PCM HAS FAILED.

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).

I HAVE A 2006 FORD F-450 AND IT WON'T START I HAVE


Take off the Fuel filter and see if it is dry. If it is dry you know its a fuel line bleeding down or a fuel pump. Prime the new filter with fuel and see if the engine will hit.

Since you replaced the Glow plugs did you test the circuit? You should be able to test each plug wire when the engine is in startup. You can take out a Glow plug and ground it with a battery jumper cable while it gets power from its wire off the controller. The plug should heat up. Or you can just test the wire with a meter.

There are crank position sensors and cam sensors I believe on this model. Check with Autozone after you do the other tests.

The last case would be the worst, jumped time or problems with timing gears. Like to know results and Good Luck.
