Electronic Fuel Control Computer Test

  1. Connect a tachometer and set parking brake. Start engine, warm to normal operating temperature and maintain engine speed of 2000 RPM. DO NOT ground carburetor switch. Connect a voltmeter to duty cycle solenoid output wire going to carburetor (green wire).
    NOTE: Do not separate the connector from the wiring harness.
  2. Disconnect electrical connector at oxygen sensor and connect a jumper wire to the harness end. Connect the other end of the jumper to a good ground. Engine speed should increase at least 50 RPM and voltmeter should indicate more than 9 volts.
  3. Hold jumper wire with one hand and with the other hand, touch the battery positive terminal. DO NOT connect jumper wire directly to battery. Engine speed should decrease at least 50 RPM and voltmeter should indicate less than 3 volts. If computer fails both tests, it must be replaced. Reconnect oxygen sensor harness.
    CAUTION: Before performing the next test, the fuel control computer must be operating properly.
