I checked the resistance of the coil, 4.8 ohms on the primary, 10750 on the secondary, so secondary resistance is OK, primary is about 4 times normal. I used a test light to check for pulses on the coil negative side while cranking the engine, and nothing. I removed distributor cap and the rotor doesn't turn. Bad lhs timing belt, which seemed odd because I loosened a few bolts to pry open the cover on both sides, and belt appeared intact. I proceeded to removing alternator and AC bracket, fan, power steering, timing covers. Lhs timing belt has no teeth, can a bad idler pulley cause this? Car has 177k miles...
