Default 2.4L Fuel Injector Questions

94 Hardbody 2.4L

I have 2 questions. First is, does anyone have the part number for the small metal clip that holds the injector connector on the injector? I think itís b4111-u7600 but after a ton of searching I cannot confirm.

Second, #4 injector is reading 6.8-7.4 ohms. Is it really bad? The service manual says 11-14 ohms is good.

The part number is, for that easily lost part, 1-800-Make the part out of a paper clip, then glue it into place.


Otherwise, I'd search online for an OEM parts diagram.

I canít seem to find a parts diagram either. The search continues..

I'll guess that they are part of the wiring harness, and not sold separately. Maybe look on eBay, etc. for replacement injector connectors, or a similar year Nissan in a junkyard.

I found 2 part numbers, B4111-U7602 & B4111-U7604 they are both still available from Nissan... if that helps

If the service manual says it needs to read between a certain resistance, then it needs to read between them.

So... yes, it's a bad injector.

The fuel injector is predominantly a solenoid. A solid core piece of metal with wire wrapped around it(turns). When the wire is energized, the electrons will open the injector opening and allow high pressure fuel to fill the cylinder. Then close back up to hold more high pressure fuel for the next cycle. This is all done under engine timing. In electronics, components or appliances, need to fall within a designed specification, or the appliance will not act right. Example, the spray nozzle of the injector which is controlled by the energizing of the wire wraps, or “turns” around the solid piece of metal rod. If the resistance reading(s) are lower than the factory specs, the resistance is beginning to not create control of the electron flow, a short. If the resistance is measured higher that the factory’s specs, a high resistance is present and would cause the solenoid not to get the threshold current needed for the component to operate properly. Therefore, creating an issue, such as the one you are experiencing. A resistor is merely a “speed bump” to slow and control electron flow. Heat from a resistor is the byproduct of energy loss , no matter the size of the resistor. Albeit a 1/8, 1/4, etc. sized resistor.

Just want to confirm that PN B4111-U7600 is the correct PN for the injector clips. Ordered some and they work perfectly.
