Ensure sufficient battery voltage (12.4 volts) is available to operate cranking and ignition systems. Disconnect wiring connector from coil pack. Connect a test light between B+ coil pack wiring connector terminal (Dark Green wire with Black tracer) and ground. See Fig 1 .
Turn ignition switch to ON position. DO NOT return ignition switch to OFF position. If test light flashes momentarily, SBEC energizes ASD relay, go to step 3). If test light does not flash, ASD relay did not energize, see appropriate TESTS W/CODES article in the ENGINE PERFORMANCE Section to check SBEC and ASD relay.
Crank engine for 5 seconds. If test light momentarily flashes during cranking, engine controller is not receiving signal. See appropriate TESTS W/CODES article in the ENGINE PERFORMANCE Section to check camshaft sensor and sensor circuits. If test light does not flash, unplug camshaft sensor connector.
Turn ignition switch to OFF position, then to ON position. Wait for test light to momentarily flash once then crank engine. If test light flashes once again, replace shorted camshaft sensor. If test light does not flash, see appropriate TESTS W/CODES article in the ENGINE PERFORMANCE Section to check crankshaft sensor/camshaft sensor 9-volt supply or crankshaft sensor 5-volt output to ground circuits.

• You smell fuel, burning insulation, or see smoke.

• Brakes feel soft, pull hard to one side, or make grinding noises.

• The engine overheats, stalls repeatedly, or misfires under load.
