6.2L and 6.5L engines are basically the same. Difference in procedures
are noted. Refer to para. 1-10 to determine engine model before ordering
replacement parts.
NOTE
l Before disassembly, fuel injection pump should be tested (para. 2-33.c,
2-34.c, or 2-35.c) on calibration stand to determine type of pump
malfunction.
l Do not disassemble fuel injection pump if no malfunction is found after
preliminary test.
l Work area should be clean, well-ventilated, and free from blowing dirt
and dust.
Fuel pump body must be thoroughly cleaned before disconnecting any
attaching components to prevent foreign particles from entering pump.
