Ignition coil PLEASE HELP!!

[racecube]

I have one or even more ignition coils broken. How can I measure the coils, what are the electical values of these parts.

Any help in short time would be great!!!!

Eddy,

Primary between 0.68 - 0.83 ohms.

Insulation, primary to enclosure should exceed 10 Meg Ohms.

Primary coil resistance difficult to measure because of a built in diode.

Best practical way to check the coil is to connect and observe for spark.

Alternatively, disconnect injectors one by one in order to detect any cylinder not firing, and which will be any not showing an effect after disconnection.
