+12v is supplied to the coil primary winding via the key switch. Primary resistance should be .72-.88 ohms. Secondary resistance as measured between the coil + primary blade and the high voltage secondary connector should be 103-13.9k ohms (k = 1000). The blades of the primary connector are oriented like the letter "T". The positive blade is the vertical part of the letter "T".

Other suspects are the power transistor and the ECU.
