| 1. Disconnect a wire from the plug - the storage battery. |
| 2. Remove the top casing of the engine (subsection 2.1 see). |
|
|
3. Disconnect колодку II plait of atomizers from колодки I plait of wires. |
| 4. Connect an ohmmeter to following contacts колодки 2: the first cylinder – contacts 7 and 5; the second cylinder – 7 and 3; the third cylinder – contacts 7 and 2; the fourth cylinder – contacts 7 and 6. In all cases resistance should be nearby 0,5 Ohm. |
| 5. If resistance of any pump-atomizer differs from specified, measure resistance directly on pump-atomizer contacts. |
| 6. For this purpose remove the top cover of a belt of a drive of a camshaft, a cover of a head of the block of cylinders, disconnect from a pump-atomizer колодку with wires and measure resistance. |
| 7. If it differs again from specified, replace the pump-atomizer. If resistance in norm, replace atomizer wires. |
