If your Honda CRX is running too lean, you can address the issue by checking and adjusting the fuel pressure. Start by inspecting the fuel pump, fuel filter, and fuel injectors for any clogs or malfunctions. If those components are functioning properly, you may need to adjust the fuel pressure regulator to ensure it provides adequate pressure. Additionally, consider checking for vacuum leaks and ensuring that the engine management system is functioning correctly, as these factors can also contribute to a lean condition.
Yes, you can replace the fuel pump in a 1985 Honda CRX Mk1 with an in-tank fuel pump from another Honda model, but compatibility is key. You'll need to ensure that the replacement pump fits the CRX's fuel tank and matches its flow rate and pressure requirements. Additionally, modifications to the wiring or fuel lines may be necessary depending on the donor vehicle. Always verify that the replacement part meets the specifications needed for optimal performance.
