Each coil tower is labeled with the number of the corresponding cylinder. 1. Disconnect the cable from the negative terminal of the battery. 2. Clearly label the spark plug wires, then detach them from the coil pack. 3. Disconnect the electrical connector from the coil pack. 4. Measure the resistance on the primary side of each coil with a digital ohmmeter. At the coil, connect an ohmmeter between the B+ pin and the pin corresponding to the particular cylinder. Compare your readings with the resistance values listed in this chapter's specifications. Replace the coil if resistance is not within specifications. 5. Measure the secondary resistance of the coil between the paired high tension towers of each group of cylinders. Compare your readings with the resistance values listed in this chapter's specifications. Replace the coil if resistance is not within specifications. And, that's it. Here is some supplemental info and the resistance specification: First, the primary resistance is checked by bridging the pins in the electrical connector. Looking at the ignition coil with the connector oriented toward the bottom, the pins are as follows, left to right: 1. Ignition coil cylinders 3 and 6 2. Ignition coil cylinders 1 and 4 3. B+ 4. Ignition coil cylinders 2 and 5 The location of the cylinders' pins also correspond to the tower location on the pack. With the same orientation, the location of each tower is thus: 315 642 Ignition coil resistance specifications: Primary resistance: 0.45 to 0.65 ohms  70 to 80 degrees F Secondary resistance: 7,000 to 15,800 ohms 70 to 80 degrees F

Replying to: silky2003 (Oct 07, 2009 11:03 am) Does it crank? Does it try to run and then just dies? Do you have spark at any/all of the plugs? Do you have fuel flow into the fuel injectors (that is, is the fuel pump working)? Was it running fine one day, then just suddenly decided not to start the next? Tell us a bit more about the vehicle? How many miles? What engine? Any previous history of a problem like this?

Replying to: silky2003 (Oct 08, 2009 6:29 am) Unfortunately, I can't tell you where to go from here. I assume the PCM (ECU) is getting +12V? I had the 3.3L in our '94 DC, but never had any problems with the ignition, so never had to replace or troubleshoot the parts you've already replaced. |
