3 and 6 glow plug failure
Hi I have a 2000 7.3 ford Excursion and I replaced the glow plugs about a year ago and now the service engine light is on and it says that 3 and 6 glow plug circuit failure. Is there a way to check the glow plugs. I also am not sure of the cylinder orders to locate three and 6. Is 2,4,6,8 on the drivers side starting at the front of the motor and 1,3,5,7 on the passengers side. Is there any other common problem in the wiring going to the glow plug. thanks

Welcome to FTE 2coolcars.
The cylinders are numbered as you described them. The four outside wires on each valvecover harness (the brown ones) go to the glow plugs. You can ohms check the plugs and UVC harness without removing the valvecover.
Seeing as you are getting an DTC from the glow plug system your glow plug control module (GPCM) might be at fault.

Thanks for the info Scott I appreciate it and I will try that. If the actual glow plug was bad would the service engine light come back on right away after I erase the glow plug fault in the computer because mine dont come back on for a couple days. Thanks Mike
