Is the coil faulty or not? “tested the and no spark either” So how did you expect to have a spark with testing?
Copied from the www.
Typically, for most automotive coils, a reading of 0.75 to 0.81 Ohms for the primary winding and 10,000 to 11,000 ohms for the secondary winding is correct. To check resistance, attach the multimeter/ohmmeter leads to the two outside poles on the primary winding. On the secondary winding, attach one lead to either of the side poles and the other to the central high tension terminal. If the readings are even slightly outside the resistance indicated in your service manual, get your ignition coil replaced.
