The simplest checks
Before checks, make sure that the vehicle is filled with sufficient fuel.
If the vehicle is equipped with an engine start coding system (immobilizer), then start the engine with other keys from the kit. If the engine starts, then the cause is a broken ignition key. Check the key in a car service.
If it is not possible to start the engine using other keys, then contact the car service, as the anti-theft system may fail.
The starter does not rotate the engine, or rotates weakly
1. Check the condition of the power cable terminals, the reliability of their fastening.
2. If the condition of the terminals is satisfactory, then turn on the interior lighting. If the lamps do not light or become dim (or go out) when the starter is turned on, the battery is discharged. In this case, start the engine from the auxiliary battery or, if the car is equipped with a manual transmission and there is no catalytic converter, the engine can be started by pushing the car. It is usually not possible to start a diesel engine by pushing with a very discharged battery.
3. If the lamps do not go out, but the engine does not start, then the engine needs to be adjusted or repaired. In this case, contact a car service for qualified assistance.
Attention! It is forbidden to start the engine by towing. Otherwise, a collision may occur after starting the engine. Models 4E-FE, 4A-FE, 7A-FE also cannot be pushed started. The neutralizer may become hot and cause a fire.
The starter turns the engine at normal speed, but the engine does not start
Gasoline engines
1. Make sure all wiring connections are secure (especially connectors on the distributor and fastening wires to spark plugs).
2. If the connections are in a satisfactory condition, then the reason for the failure at start-up is the re-enrichment of the mixture and the filling of the cylinders with gasoline. In this case, follow subsection 1.35.1.
Diesel engines
3. If you tried to start the engine with an empty tank, you will need to remove air from the fuel system (see subsection 1.35.2).
4. If the air is removed but the engine does not start, repair is required. In this case, contact a car service for qualified assistance.
