1. At violation of serviceability of functioning of system of ignition before starting diagnostics of a condition of the distributor, execute the following preliminary checks:

a) Check a condition of terminal connections of the battery and reliability of a tightening of clips of fastening of tips of wires for them;
b) Check a condition of the battery (see the Section Check of a State and Replacement of the Battery), in case of need make its replacement;
c) Check an external condition of VV of wires of the distributor and coil of ignition and reliability of their fastening on plugs;
d) At the corresponding complete set check a condition of fusible inserts in the assembly block located in a motive compartment of the car (see the Head Onboard electric equipment). Replace the fused elements.

2. Check serviceability of sparking on spark plugs. If the engine is turned, but not started, disconnect VV a wire from one of spark plugs and connect it to the special calibrated tester (ask in shops of automobile accessories). Fix a clip of a tester on a bolt or a metal arm of the block of the engine, having reliably grounded it thereby on weight. In the absence of near at hand the calibrated ignition tester, disconnect a wire from a spark plug and, holding it nippers with reliably insulated handles, delay a rubber tip up a wire and bring the contact plug to well grounded point on the block on distance about 6.4 mm. At an engine provorachivaniye between an electrode and the case the VV tester/plug of a wire and weight well noticeable spark of bright blue color has to slip.

3. If the spark makes the way regularly and its intensity does not raise doubts, repeat check for VV of wires of the remained spark plugs. This check allows to confirm serviceability of a cover and the runner of the distributor, without excluding, however, probability of failure actually of candles therefore turn out the last and make check of their state according to the description provided in the Head Nastroyki and routine maintenance of the present manual.
4. In the absence of a spark uncover the distributor and check its state, as well as a condition of the runner (see the Head Nastroyki and routine maintenance). In the presence of moisture traces carefully wipe surfaces of a cover and the runner pure dry rags, then establish a cover on a place and repeat sparking quality check;
5. If removal of moisture did not lead to correction of a situation (sparking on former insufficiently intensively or is absent at all), on the V6 models it is necessary to disconnect a secondary wire of the coil from a distributor cover and to connect to it an ignition tester (do not forget to connect wire VV to all candles). Repeat the check procedure described above.

In the absence of near at hand tester of ignition alternative check of a wire of the coil is made also as well as in a case with VV wires of spark plugs by leading of the plug to weight on distance about 6.4 mm.

6. In the absence of sparking on 4-cylinder models check a condition of a spring and the contact coal button in a distributor cover for existence of traces of progar and mechanical damages. in case of need replace a distributor cover.
7. If this time there is a normal sparking, therefore, the cause of failure lies in malfunction of a cover of the distributor, its runner or the corresponding candle wires (see the Head Nastroyki and routine maintenance).

8. In the absence of sparking and at this stage, it is necessary to pass to check of contact connections of primary contour of the coil of ignition, - estimate a condition and reliability of fastening of plugs. Check serviceability of giving of primary tension for the coil from the ignition switch/lock for what measure tension on a positive side of the coil. In view of the fact that on 4-cylinder models the coil of ignition is built in in the distributor, it is necessary to uncover the last, to disconnect wires from the coil, then to check existence of tension of the battery on the plug of a black-yellow wire. Make necessary corrections, then repeat check.

9. If tension on the coil takes place, and sparking is still absent, measure resistance of primary and secondary windings of the coil (see the Section Check of a State and Replacement of the Coil of Ignition). In case of identification of breaks (the infinite indication of an ohmmeter), replace the coil.
10. If the coil as it should be, serviceability of functioning of the module of management of ignition (ICM) (see the Section Check of Serviceability of Functioning and Replacement of the Module of Management of Ignition (ICM)).
11. Performance of further checks of PGM-IG system should be charged to experts.
