Injector Fuel Leakage Inspection

WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2002 Mazda Tribute, 2002 Mazda Protege5, 2002 Mazda Protege, 2002 Mazda Millenia, and 2002 Mazda MX-5 Miata. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Do not reuse fuel injector "O" rings. Replace with NEW "O" rings.

Release fuel pressure. See FUEL PRESSURE RELEASE . Remove fuel rail assembly. Reconnect fuel lines to fuel rails. Disconnect inertia fuel shutoff switch 3-pin harness connector. Install fused jumper wire between battery positive and inertia fuel shutoff switch terminal No. 2 (Pink/Black wire) to run fuel pump. Check for leaks at fuel injectors. If fuel leakage is more than one drop per 2 minutes, remove leaking injector and check for faulty "O" rings or damaged fuel rail. If o-rings and fuel rail are okay, replace fuel injector. Repair as necessary.
