See Figure 1
- Remove the coil wire from the distributor cap. Using non-conductive ignition pliers, hold the end of the wire about 1 / 4 in. (6mm) away from a good engine ground point.
- Have a helper crank the engine. Check for a spark between the coil wire end and the ground point.
- If there is a spark, it must be constant and bright blue in color.
- Continue to crank the engine. Slowly move the wire away from the ground point. If arching at the coil tower occurs, replace the coil.
- If the spark is good and no arcing at the coil tower occurs, the ignition system is producing the necessary high secondary voltage.
- Check to make sure that the voltage is getting to the spark plugs. Inspect the distributor cap, rotor, spark plug wires and spark plugs.
- If all of the components check okay, the ignition system is probably not the reason why the engine does not start.
- Check the fuel system and engine mechanical items, such as the timing belt.
REMOVAL & INSTALLATION
See Figures 2, 3, 4, 5 and 6
The ignition coil is located at the back of the intake manifold.
- Disconnect the negative battery cable.
- If necessary, remove the windshield wiper/motor module assembly. Refer to Chassis Electrical for this procedure.
- Disengage the wiring harness connector from the ignition coil.
- Disconnect the ignition wire from the coil.
- Remove the coil mounting bracket bolts, then remove the coil and mounting bracket assembly from the vehicle.
- The ignition coil can be separated from the mounting bracket.
- If separated, loosely mount the ignition coil to the mounting bracket.
- Loosely install the coil and mounting bracket assembly to the intake manifold. Tighten the coil mounting bracket-to-intake manifold bolts to 115 inch lbs. (13 Nm) and the ignition coil-to-mounting bracket fasteners to 96 inch lbs. (10 Nm).
- Connect the ignition wire to the coil.
- Engage the wiring harness connector to the ignition coil.
- If removed, install the windshield wiper/motor module assembly.
- Connect the negative battery cable.
