FUEL INJECTION SYSTEM
CAUTION: The fuel system incorporates
fine metering components that would be
affected by any dirt in the system;
therefore it is essential that working conditions
are scrupulously clean. If it is necessary to
disconnect any part of the fuel injection system,
the system MUST be depressurized. All openings
left open after the removal of any component from
the fuel system, MUST be sealed off to prevent
ingress of dirt.
ENGINE SETTING PROCEDURE
If a major overhaul has been undertaken of the fuel
injection/engine system, the following check and
adjustments must be carried out before attempting to
start the engine.
1. Spark plug gaps.
See ENGINE TUNING DATA,
Information, Engine 3.9 V8i or
See ENGINE TUNING DATA, Information,
Engine 4.2 V8i
2. Ignition timing.
See ELECTRICAL,
Adjustment, Ignition Timing
CAUTION: Catalyst vehicle - if the engine
is misfiring, it should be immediately shut
down and the cause rectified. Failure to do
so will result in irreparable damage to the
catalysts.
NOTE: If the previous checks and
adjustments are satisfactory but the
engine will not start, the ignition and fuel
injection electrical circuits must be checked using
the appropriate recommended equipment.
