Ignition and Fuel Injector Circuits:

CIRCUIT DESCRIPTION
The ignition system uses a waste spark method of spark distribution. Refer to Ignition System for waste spark description.
During cranking, the ignition control module monitors the crankshaft position sensor signals. The signals are used to determine the correct cylinder pair to spark first. After the crankshaft position sensor signals have been processed by the ignition control module, it sends a fuel control reference pulse to the Powertrain Control Module (PCM). When the PCM receives this pulse it will command all eight injectors to open for a priming shot of fuel in all cylinders. After the priming, the injectors are left "OFF" for the next eight fuel control reference pulses from the ignition control module (two crankshaft revolutions). This allows each cylinder a chance to use the fuel from the priming shot. During this waiting period, a cam pulse will have been received by the PCM. Now the PCM begins to operate the injectors sequentially based on true crankshaft position. However, if the cam signal is not present at start-up, DTC 41 will set and the PCM start fuel delivery in random pattern with a 1 in 6 chance that fuel delivery is correct.
The crankshaft position sensor signals are used only by the ignition control module. It is used for spark svnchronization and to initiate reference pulses only (not passed to PCM).

CHART TEST DESCRIPTION
Number(s) below refer to circled number(s) on the diagnostic chart.
1. A blinking injector test light verifies that the PCM is monitoring the fuel control signal and attempting to activate the injectors.
2. The crankshaft position sensor has been verified as functioning properly, as is evidenced by the blinking injector test light. A fuel pressure test, at this point, will separate the diagnostic path into either a fuel related fault or ignition system fault.
3. By testing for spark on plug cables 1, 3, 5, and 7, each ignition coil's ability to produce at least 25,000 volts is verified.
4. By testing the problem coil's control circuit with a test light, a determination can be made as to the problem coil being faulty or the ignition control module's internal driver for that coil being the source of the complaint.
5. Check for B+ to injectors.
6. Checks the PCM's ability to operate the injector(s) driver.
7. Checks power and ground circuits for the ignition control module.
8. Checks crankshaft position "A" sensor and connecting wires.
9. Checks crankshaft position "B" sensor and connection wires.
