How to Test TYDA Injectors

Leak-off test: Connect clear hoses to the injector return lines and compare fuel volumes at idle. The injector returning the most fuel is likely worn.

Resistance check: Measure resistance across the injector connector pins with a multimeter. Compare to manufacturer specs.
