In a 1986 Toyota MR2, the fuel injector pulse is controlled by the engine's electronic control unit (ECU), which manages the timing and duration of the injector's operation based on engine conditions like RPM, temperature, and throttle position. If you're troubleshooting injector pulse issues, you can check the ECU for fault codes, inspect the wiring and connectors for damage, and use a multimeter or oscilloscope to test the injector's voltage and pulse signal. Proper fuel supply and pressure should also be verified to ensure the injectors function correctly.
