Test 3 - Failure to Start

Wiring Harness Coil Connector:

1. Determine that sufficient battery voltage (12.4 volts normal) is present for cranking and the ignition system.
2. Connect voltmeter to the wiring harness coil connector at the B+ pin.
3. Crank the engine for five seconds while monitoring the voltage at the B+ connector terminal.
^ If the voltage remains near zero during the engine period of cranking, refer to TEST 4 - AUTO SHUTDOWN (ASD) RELAY
^ If voltage is at "near-battery" voltage, and drops to zero after 1-2 seconds of cranking, refer to COMPUTERIZED ENGINE CONTROLS for further diagnosis of the cam and crank sensors.
^ If voltage is at "near-battery" voltage during the entire five seconds, turn the key OFF, remove the Single Board Engine Controller (SBEC) 60-way connector. Check the 60-way connector for any loose, dirty or broken terminals. Plug the 60-way connector back into the SBEC and try to start vehicle. If it does not start refer to COMPUTERIZED ENGINE CONTROLS for further diagnosis.
