GENERAL INFORMATION

Before conducting check be convinced that the safety lock No. 35 did not fuse, the wire connecting the engine to "weight" did not break and was not oxidized, the rechargeable battery is charged (the minimum tension 11,5 B), the relay of the fuel pump did not fail. At engines 1,4l, 55 and 74 kW, besides, check that did not fail: sensor of frequency of rotation of a bent shaft and sensor of position of the camshaft.

PERFORMANCE ORDER
1. Remove the top casing of the engine (see subsection 2.1).
2. At engines of 1,4 l, 55 and 74 kW disconnect a block with wires from the ignition module.
3. Disconnect blocks with wires from nozzles.
4. Connect the electric indicator of tension with a light-emitting diode to contacts of the block 1 disconnected from a nozzle 2 first cylinders (3 – tension indicator with a light-emitting diode).
5. Turn the engine a starter, at the same time the light-emitting diode has to blink. It means that food on a nozzle moves. In the same way check other nozzles.
6. If at an engine provorachivaniye the diode does not blink, connect tension indicator to contact of 1 block (2 – the second contact) disconnected from a nozzle of the first cylinder and to "weight" (and – engines of 1,0 l, 37 kW and 1,4 l, 50 kW; – engines of 1,4 l, 55 and 74 kW). Turn the engine a starter, the light-emitting diode has to blink; if does not blink, check wires for break and short circuit. Similarly check other nozzles.
7. If there is no break in wires, check resistance of nozzles. For this purpose connect an ohmmeter to contacts of a nozzle and measure resistance. For engines of 1,0 l, 37 kW and 1,4 l, 50 kW it has to be 14–20 Ohms; for engines of 1,4 l, 55 and 74 kW – 14–17 Ohms (at 20 °C, at the heated-up engine resistance is about 4-6 Ohms higher). If resistance differs from specified, replace nozzles.
