How to test and replace a front fuel injector on a Toyota MR2?

Disconnect the electrical connector from the cold start injector, noting that the wire clip must be expanded before unlocking the plug from the injector terminal. Ground the connector with a test light and turn the ignition key to Start; the light should illuminate if the circuit is functioning properly. If it does not, inspect the cold start injector electrical circuit for any issues such as an open, short, or bad connection. Remove the two mounting bolts and pull the injector out of the plenum without disconnecting the cold start tube banjo fitting. Reconnect the electrical connector to the injector, place a small container underneath, and turn the ignition key to Start; if the injector is working correctly, it will squirt fuel into the container. If it does not, it needs to be replaced. Disconnect the electrical connector again and check the injector for continuity with an ohmmeter, ensuring the resistance between terminals is between 3 to 5 ohms; if not, replace the injector. Temporarily install the injector mounting bolts, then use a backup wrench to break loose and disconnect the cold start injector tube banjo fitting. Disconnect the electrical connector, remove the two mounting bolts, and take out the injector. Installation follows the reverse order of removal.

How to check and replace the front fuel injector on a Toyota Supra?

Unplug the electrical connector from the cold start injector. Using an ohmmeter, measure the resistance of the cold start injector and compare your measurement to the specific resistance; if the indicated resistance is outside the indicated range, replace the cold start injector. Relieve the system fuel pressure. Detach the cable from the negative battery terminal, taking caution if the stereo in your vehicle is equipped with an anti-theft system. For models from 1982 through 1986, remove the air intake chamber, as the cold start injector is located on the underside of the air intake chamber near the throttle body. Remove the banjo bolt and sealing washers, and detach the fuel hose banjo fitting from the cold start injector. Remove the cold start injector retaining bolts, then take out the cold start injector and gasket from the air intake chamber. Installation is the reverse of removal; ensure to use a new flange gasket and new sealing washers at the fuel line banjo bolt, and tighten the banjo bolt to the specific torque.
