Fuel injectors are flow tested and then color coded (RED,
BLUE, or YELLOW) based on upon how much fuel the injector
flows during the test.
When replacing a faulty fuel injector, always replace with an
injector with the same color code. If replacing with an injector
with a different color code, all four fuel injectors must be
11.32
-22_F - +248 _F (-30_C - 120_C)
2.4 - 2.6KΩ@ 68_F (20_C)
(Measure in stirred water)
29 ft.lbs. (39.2Nm)
12Ω @ 68_F (20_C)
replaced with the new color so all four injectors are the same
color.
After replacing all four injectors, the ECU must be reflashed so
the fuel calibration map matches the new color coded fuel
injectors.
Reference Chapter 4 for fuel injector replacement procedures.
CAUTION
NEVER RUN THE ENGINE WITH DIFFERENT COLOR
FUEL INJECTORS. SEVERE ENGINE DAMAGE WILL
OCCUR.
ALWAYS VERIFY THE ECU CALIBRATION FILE
MATCHES THE FUEL INJECTOR COLOR CODES.
