- Disconnect the ignition coil connector and check for dirt, corrosion or damage.
- Substitute a known good coil and check for spark using the spark tester.
- Crank the engine and check for spark.
- Turn the ignition switch OFF .
- If a spark did occur, measure the resistance of the ignition coil wire; replace it if the resistance is greater than 7,000 ohms per foot. If the readings are within specification, replace the ignition coil.
- If no spark occurs, the problem is not with the coil.
REMOVAL & INSTALLATION
See Figures 1, 2, 3 and 4
- Disconnect the negative battery cable.
- Tag and disconnect all wiring from the ignition coil.
- Remove the ignition coil-to-bracket bolts, then remove the ignition coil.
- If necessary, at this time the radio ignition interference capacitor can be removed from the ignition coil.
- If necessary, install the radio interference capacitor onto the ignition coil. Tighten the mounting bolt to 25-35 inch lbs. (2.8-4.0 Nm).
- Position the ignition coil onto the mounting bracket, then install and tighten the mounting bolts to 25-35 inch lbs. (2.8-4.0 Nm).
- Attach all wiring to the ignition coil, then connect the negative battery cable.
