Necessary precautions:
- A). Do not disconnect the battery while the engine is running.
- b). Perform decompression before depressurizing the system.
- V). Before removing any unit of the system, disconnect the battery from the ground and turn the ignition key to the Off position.
- G). Wiring harnesses"systems must run at least 10 mm from other bundles (including antenna cable),
- d). Check the reliability of all connections, as bad contacts will spark from a breakdown in the candles and the ignition unit will fail.
- e). Do not press the throttle pedal before starting the engine.
- and). Keep in mind that the operation of the fuel pump is controlled by several relays. After the engine is stopped, the pump is switched off by pressure and voltage drop signals on the generator.
