Opps just saw you were askin about the Coil Pack
Here is the stuff for that.
Primary resistance 0.3 - 1.0 ohms
Secondary resistance 6.5 - 11.5 kohms.
Disconnect the electrical connector from the coil. Connect an ohmmeter across the coil positive terminal and each negative terminal. The resistance should be as stated above.
Note: Each coil pack is paired according to the campanion cylinders. Be sure to check resistance with these designated terminals only.
4.2L V6 ..........1/5, 2/6, 3/4
4.6L engines .....7/4, 8/2, 1/6, and 3/5.
Connect an ohmmeter between the secondary terminals (the one that the spark plug wires connect to) of each coil pack. The resistance should be as stated above.
