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) |
