Injector testing

Injector Testing

Chicking the injectors resistance wiith multimeter ohms conected the meter probo to the injecter power feed and the results are in below chart.
Common valves:
without resisto: 14- 17.0 ohms
with resistor 14.0 - 17.0 ohms
i had checked the resistance without resistor.

Injectror electrical test

Now i wired up to power supplay in order to hear audible clicking sound that telling us that injectors are working . One injecter is not clicking the result is below chart.

Injector number	1	2	3	4
Injector operation audible	OK	not	OK	OK

could give the State any other engine problem that same result as an injector not firing.

The engine problem could be give the same result as injector not firing it cuold be:
- Damaged coil
-Faulty HT lead
-Faulty sprk plug
-Faulty fuel pump

Injector number	1	2	3	4
Manufactures specification  ohms	14.0 – 17.0 ohms	14.0 – 17.0 ohms	14.0 – 17.0 0hms	14.0 – 17.0 ohm
Winding resistance ohms	14.3 ohms	14.4 ohms	14.3 ohms	14.4 ohms
