2.14.8. Diagnostics of malfunctions of system of ignition

REASON
ELIMINATION METHOD
The engine is started badly or not started absolutely
There is no ignition spark. The distributor cover damp, is polluted To clean and dry up a cover of the distributor and to sprysnut from within аэрозолью for start of the dampened engine
Cracks in a distributor cover, traces of podgoraniye To replace a distributor cover
The graphite sliding contact in an ignition distributor cover is worn-out To replace the graphitic sliding contact
The distributor runner is faulty To replace the distributor runner
Distributor runner resistance is too high To replace the distributor runner
Too big resistance in wires of high voltage and candle plugs To replace wires of high voltage and candle plugs
Candle plugs are attached not in an operating procedure of cylinders To put on candle plugs in an operating procedure of cylinders: 4-cylinder engine: 1–3–4–2, 5-cylinder engine: 1–2–4–5–3
Candles as a result of repeated attempts of start are filled in with fuel To remove and dry candles
Candles outside damp and dirty Candles to clean, dry. To put on silicone protective caps spark plugs and plugs
Tension of the coil of ignition is not enough To check an electrical wiring of the transformer of high voltage (the ignition coil) for reliability of fastening and good contact
Cracks on the ignition coil, traces of podgoraniye To replace the transformer of high voltage
Loss of tension as a result of a contact of electric connections or conducting with engine hoses It is correct to arrange conducting
There is no giving of current to the control unit To check an electrical wiring according to the electrical circuitry (see subsection 10.20.8)
