Breakerless Distributor The distributor is driven by the camshaft of the engine. The distributor shaft has a trigger in place of a breaker cam. The PICKUP ASSEMBLY mounted in the distributor is electrically connected to the ELECTRONIC CONTROL MODULE. PickUp Assemblv The assembly consists of a pickup coil, stator pole, and a permanent magnet. The assembly creates a magnetic field. The trigger has four teeth, 90 degrees apart. As a tooth passes through the magnetic field, it causes an electrical impulse in the pickup coil. This impulse is fed to the ELEC TRONIC CONTROL MODULE for controlling the coil primary circuit.

TROUBLESHOOTING

NOTICE: The following Spacial Notes apply to the Marelli Electronic Ignition System: - 00 Not energize the ignition unless the coil support base is properly grounded. - Do Not crank the engine with the coil wire disconnected;
- Do Not disconnect the coil wire with the engine running. - 00 Not start the engine with the instrument cluster disconnected. - 00 Not ground the coil lead to the tachometer (black wire), or use diagnostic equipment (or jumper wires) to ground the primary circuit. - 00 Not test for current or voltage by "flashing" terminals to each other or to ground. - The leads to the distributor pickup may be disconnected while the engine is running without damaging the system. - 00 Not disconnect the battery cables while the engine is running; although the ignition system can wi thstand a peak of 300 volts (for a period of microseconds), the charging system (alternator! electronic voltage regulator) will be damaged. IF STARTER CRANKS BUT ENGINE WILL NOT TURN OVER: Check for 12V at terminal 16 of the IGNITION Check for proper grounding of the IGNITION COIL support mounting using an ohmmeter. Connect meter between coil

14 ",!

support mounting and negative terminal of battery. Resistance should read.2 ohms or less. Check IGNITION COIL resistance with ohmmeter. First disconnect wires from coil. To measure primary coil, read between terminal 16 and terminal D. Reading should be 0.75 to 0.81 ohms. To measure secondary coil read between terminal D and output to distributor. Reading should be 10,000 to 11,000 ohms. Check distributor pickup coiL Remove connector from the ELECTRONIC CONTROL MODULE and, with an ohmmeter. measure resistance of pick.up coil. The reading between the pins of the connector should be 700 to 800 ohms. Then move one of the meter leads to the distributor body to check pick-up insulator. Meter should read infinity (. ). Check the gap between stator pole and the teeth of the trigger with a nonmagnetic feeler gauge. Reading should be 0.020-0.024 in. (0.5 to 0.6mm). Check the ELECTRONIC CONTROL MODULE. Should only be checked after the pick-up coil has been checked to be good.

CIRCUIT OPERATION With Manual Tranamission Battery voltage is applied at all times to terminal 30 of the SOLENOID, and terminal 30 of the IGNITION SWITCH, When the IGNITION SWITCH is moved to "Start," current flows through terminal 50 of the SOLENOID, and both the hold-in and pull-in windings (to ground). The holdin and pull-in windings work together magnetically to pull in the shifter. Current through the pull-in winding also flows through the MOTOR. The MOTOR begins to turn slowly to insure easy meshing of the gear teeth. As the gears mesh, the SOLENOID contacts close. This applies full battery voltage directly to the MOTOR through terminal 30. When the IGNITION SWITCH is released from "Start," current from the IGNITION SWITCH stops. Current from the BATTERY through the SOLENOID contacts now flows in the ,reverse direction through the pull-in winding, then continues in normal direction through the hold-in winding. The magnetic force of the hold-in winding is opposed and cancelled by the reverse current through the pull-in winding. The drive mechanism is spring-releaeed and opens the SOLENOID contacts. Voltage to the MOTOR is cut off. With Automatic Transmission With automatic transmission, battery voltage is also applied to terminal 30 of the STARTER RELAY at all times. When the IGNITION SWITCH is moved to "Start," voltage is applied through the STARTER RELAY coil, GRY IRED wire, and RED

TEMfERATUREINCREASES
The Fuel Injection System senses the amount of fuel needed for the proper air/fuel mixture. The fuel is sprayed into the air stream in the intake manifold. Fuel Injection is made up of three major systems: the fuel system, air system and electrical system. A brief description of each major system will aid in understanding how the entire Fuel Injection System operates electrically.

The fuel system consists of four FUEL INJECTORS, one for each cylinder. The injectors deliver pulses of fuel at the correct pressure to the intake manifold and are controlled by the ELECTRONIC CONTROL UNIT (ECU). The system also provides additional fuel for cold starting. This is done by the COLD START VALVE, which is controlled by the THERMO TIME SWITCH. The COLD START VALVE operates with the IGNITION SWITCH in "Start" and the THERMO TIME SWITCH closed.

The air system measures the amount of air drawn into the engine, as well as its temperature, and provides this data to the ECU as input signals. The system also provides bypass air circuits for cold starting. The AIR FLOW SENSOR contains an AIR FLOW POTENTIOMETER, FUEL PUMP SWITCH and an AIR TEMPERATURE SENSOR. The AIR FLOW POTENTIOMETER is linked to a plate which senses air flow into

Voltage is applied at all times through FUSE I to the REMOVE KEY SWITCH. If the key is in the IGNITION SWITCH, the voltage is applied through the WARNING CHIME, SEATBELT RELAY. and BLK/VIO wires to the DOOR JAMB SWITCHES. When either door is opened, its DOOR JAMB SWITCH closes. This grounds the circuit and the WARNING CHIME sounds.
CIGAR LIGHTER/REMOVE KEY WARNING/SEATBElT WARNING/BRAKE WARNING

Seatbelt Warning

When the IGNITION SWITCH is turned
to "Start" or "Run," current follows three paths through FUSE A to ground: 1)
FASTEN SEATBELT INDICATOR, DK BLU/RED wire and SEATBELT TIMER to G3; 2) SEATBELT TIMER terminal to G3; and 3) SEATBELT RELAY coil, DK BLU/RED wire and SEATBELT TIMER to ground. The first path lights the indicator. The second path operates the timer and opens the other two paths after about five seconds. The FASTEN SEATBELT INDICATOR will go off after 5 seconds regardless of the seatbelt switch. The third path operates the relay and pulls in the relay contacts. If the DRIVER'S SEATBELT SWITCH is closed, it grounds the WARNING CHIME. The WARNING CHIME sounds until the belt is buckled or the timer opens the current path.

Brake Warning

I f the park brake is on, current in the second path flows through the PARK BRAKE SWITCH (to ground). The indicator goes on as a warning. The third path warns of low brake fluid level.
