Failure To Start Test: 3.3L

  1. Ensure sufficient battery voltage (12.4 volts) is available to operate cranking and ignition systems. Connect voltmeter between B+ wiring harness coil connector and ground. See Fig 1 .
  2. Crank engine for 5 seconds while monitoring voltage at B+ terminal. If voltage remains near zero during entire period of cranking, see appropriate G - TESTS W/ CODES article in this section to check SBEC and ASD relay.
  3. If voltage is near battery voltage and drops to zero after 1-2 seconds of cranking, see appropriate G - TESTS W/ CODES article to check cam and crank sensor circuits to SBEC.
  4. If voltage remains near battery voltage during entire 5 seconds, turn ignition off. Disconnect SBEC 60-pin connector. Check 60-pin connector for loose terminals (push-outs).
