Here are directions for checking the coil. NOTE: If it is bad, the entire distributor needs replaced. Also, have you tried replacing the pick up coil in the distributor?
Here are the directions:
The ignition coil is mounted in the distributor.
1.Disengage the wire(s) from the coil.
2.Use an ohmmeter, connected as illustrated, to measure the resistance on the primary side of the coil; the resistance should be 0.5-0.7 ohms.
3.Use an ohmmeter, connected as illustrated, to measure the resistance on the secondary side of the coil; as illustrated. the resistance should be 20-31 kilohms.
4.If the resistance readings are not within specifications, the coil is defective and the distributor assembly must be replaced.
5.If resistance readings are within specifications, there may be a larger problem with the EEC system. It may be necessary to have the system further tested (because of the extensive knowledge, experience and equipment necessary to perform this testing) by a professional automotive technician.
NOTE: The EEC is the electronic engine control unit. There is a relay in the power distribution box under the hood. You may want to check that too.
Let me know what you find.
