Hi,

(97 xj6)

Is there a proper procedure to be followed before removing fuel injectors?
Should I be prepared for much fuel out of the fuel rail?

 

Hi ocean_view,

You can depressurize the fuel system by first removing the fuel filler cap to relieve any pressure or vacuum in the tank, then remove the fuel pump relay, start the engine and let it run until it dies. Disconnect the negative battery cable before proceeding to remove the fuel rail and injectors. A little fuel will spill out when you disconnect the inlet hose and Fuel Pressure Regulator (FPR), so stuff an old towel under each fitting before you loosen it.

The fuel pump relay is in the trunk fuse box - it's location is shown on page 26 of the Electrical Guide (page 27 of the .pdf file), which you can download here:

The injectors have 'O' rings at both ends so they are just 'trapped' between the rail and manifold.

Be sure to lube the 'O' rings before re-assembly. Unless they are damaged you should be able to re-use.

Don, thank you for the proper procedure and the link.
Bob, thank you for letting me know about how the injectors are mounted.

I will post an update once they are removed and cleand.
