Fuel injectors

[Cp13]

Does anyone know what should the ohm be on the fuel injectors of a 06 m45. Another question for some reason only 3 fuel injectors are showing a leak would I have to replace all or can I just do the three

Hi there,

I believe you can find this information in the factory service manual. See the FAQ link in my signature for a link to the FSM.

As for which ones to replace...I'd assume as long as the other three have the same 'flow rate', you'd be fine. But you'd have to get them checked out to insure that.

I can't find the resistance specs in the service manual, but yes, you can replace only 3. Be aware that the upper and lower injector O-rings are different. Fuel tube side should be black and nozzle side is green.

I had trouble finding the green O-Rings. I had to go to a Nissan dealer, and the O-rings he gave me are brown, not green!
I gave the parts guy the Infiniti part # for what I believe to be the correct nozzle side O-Ring # 16618-AX200, and the one's he gave me are brown!

I have a new Hitachi Fuel Injector, Hitachi Part # FIJ001, it came with the O-Rings installed.
NOTE: Please re-check # for your needs, I could have wrong #
As BC mentions, on the new Hitachi Inj., the lower injector O-Ring is geen, as it should be. I am glad now I did not have to install any of my brown rings at all!

the resistance reading on the above new Hitachi injector is 12.3 ohms on my trusty Radio Shack DVOM 22-820!
