The ignition and injection system wires must be disconnected and connected only when the ignition is switched off. This also applies to the measuring instrument wires.
It is permissible to use a device for accelerated battery charging for starting the engine for no more than 1 minute at a maximum voltage of 16.5 volts.
Never disconnect the battery while the engine is running.
When charging the battery using a fast charger, disconnect the battery from the vehicle's electrical system.
Before checking the electronic injection system, it is necessary to make sure that the ignition is in order, that is, the ignition and spark plugs meet the requirements.
Do not start the engine at temperatures above +80°C (drying chamber temperature). Wait until the car cools down.
Ensure that the injection system plug connections are in perfect condition.
When checking compression, turn off the voltage supply to the fuel pump relay, remove the relay from position 12 of the relay board. Additionally, remove the high-voltage wire (terminal 4) from the ignition distributor and short it to ground.
Be careful when working with injection systems
Before disconnecting, thoroughly clean the connection points and areas near these connections with fuel.
Place the removed parts on a clean base and cover with film or paper. Do not use lint-free cloths for this purpose!
Exposed parts should be carefully covered or sealed unless urgent repairs are being performed.
Install only clean parts. Remove spare parts from packaging only immediately before installation.
If possible, do not work with compressed air when the supply system is open. Do not move the vehicle if possible.
