How to Replace a Fuel Injector in a Kia Spectra

The fuel injector in a Kia Spectra mixes fuel with air under pressure and rendered carburetors obsolete during the late 1980s. A fuel injector has programmable firmware that allows the same hardware to handle different fuels. The fuel injector consists only of a nozzle and valve; it still requires a pump to deliver fuel into the engine.

Instructions

1

Determine which fuel injector your Kia Spectra will need. This depends not only on the make and model, but also the engine size. All versions of the Kia Spectra have a 2.0L engine.

2

Relieve the fuel system pressure and disconnect the negative battery cable with a socket wrench. Detach the fuel injector electrical connectors and remove the fuel lines from the fuel rail.

3

Disconnect the bracket for the accelerator cable with a socket wrench so you can move the accelerator cable aside if needed. Loosen the fuel rail retaining bolts with a socket wrench and lift the fuel rail out of the engine compartment with the injectors still attached.

4

Remove the retaining clips for the fuel injectors and take out the fuel injectors. Remove and discard the old O-rings.

5

Lubricate the new O-ring seals with clean engine oil and install the new fuel injectors. Fasten the fuel injector retaining clips and install the fuel rail mounting bolts with a socket wrench.

6

Replace the accelerator cable bracket if removed. Connect the fuel lines and the fuel injector electrical connectors. Attach a negative battery cable with a socket wrench.
