Ignition Coil Primary Resistance
Disconnect ignition coil 3-pin connector (located in front of intake manifold). Disconnect power output stage 3-pin connector (located on right side of engine compartment firewall). Measure resistance between matching terminals of each connector (terminal No. 1 to 1, 2 to 2, and 3 to 3). See Fig 1 . If resistance is not 0.5-1.0 ohm, replace appropriate coil.
