We connect the fuel pipes to the ramp and connect its electrical connector.
Having placed transparent flasks under the injectors, we turn the engine with the starter.
The spray patterns and the amount of fuel injected into each flask over a given period of time should not differ significantly.
We check each injector separately by disconnecting the electrical connector from it. After turning on the ignition, we supply it with 12 V voltage from the battery using two wires.
A characteristic stream should flow from the nozzle sprayer.
After disconnecting the power from the injector, we check whether fuel is leaking through the nozzle hole.
We check the resistance of the injector winding with a tester.
It should be within 11-15 Ohms.
If the electrical resistance of the injector does not meet the standard, the performance and spray pattern differ greatly from other injectors, and if the injector is leaky, it must be replaced.
