GENERAL INFORMATION

If there was a malfunction in fuel system, then at first check that all electric sockets are reliably connected and protected from corrosion. Also check, purity of the air filter, a state and a gap in spark plugs, correctness of adjustment of valvate gaps, a compression in engine cylinders, installation of a corner of an advancing of ignition and purity of hoses of air supply in the engine.

PERFORMANCE ORDER
1. Pick up the air inlet phone from the case of a throttle and check existence of a carbonaceous raid in the throttle case. If necessary, using aerosol solvent, clear a carbonaceous raid.
2. Using a stethoscope, check work of fuel nozzles on presence of clicks during the work of nozzles.
3. If there is a suspicion that the fuel nozzle does not work, connect a LED sampler to contacts of a fuel nozzle and during the operation of the engine check that the LED sampler blinks.
4. Remove the electric socket from a fuel nozzle and check resistance of a fuel nozzle.
5. If actions for check of system of injection do not help to reveal malfunction of fuel system, then it is necessary to make check and repair of fuel system at service station.
