Does anyone have a good part number for a 2005 LR3 coil pack wiring harness? I need to replace mine but I am having a hard time finding it or an alternative.

Thanks,

 

V6 or V8

 

It's a V8

 

The V8 has no coil packs, just coils. I have a shop manual but it does not show part numbers. You may be better off calling a Rover dealer, they are the only ones that can probably get the harness anyway. Why do you have to replace yours though? Harnesses really dont go bad and are easily repairable.

 

Right Coil wiring harness, is what i am looking for. I have replaced all the coils, and the harness looks worn. I chased cylinder misfire on two coils before changing all of them. Now 5 months later number 1 cylinder misfire is back. I figured the harness was the next possible issue after spark plugs, coils and intake cleaning. The fuel injection seem to the working fine also. I also asked the dealer about the harness when I replaced the heater hose assembly.

 

I doubt the harness is bad. Did you save any of the older good coils? Can easily swap one to check. Or you can move a couple existing ones around. If they were inexpensive coils, its very possible one failed already.

 

Ok recap to save time and questions, I replaced 3 of the coils as they started showing misfire codes, They did this about a month apart. I decided to replace all of the rest because the vehicle has 180k. I did the spark plugs,wheel hub, heater hose assy, hood latch, air compressor, cleaned the air intake, cleaned out the sunroof drains, fixed the AC duct drain on the driver side and changed the oil. Now I am well aware on how to troubleshoot a coil and have one to replace the one currently misfiring. I did this the first time around. I say all that to say before I purchased this Lr3 I don't think it was taken to the shop for regular maintenance. I have a Gap IID tool reader that I am using to verify the information. If you have any suggestions on what it could be let me know.

Thanks,

 

The ECU fires the coils, I would pull the battery and check all the connectors back there for the computers. They tend to corrode, mainly if the battery is not vented properly.
