2008 Sedan no spark

[EBeck]

Hello, My wife's 2008 Yaris sedan suddenly stopped while driving. I turns over but there is no spark. No codes stored in the ECU. Dash lights look normal. I checked all of the fuzes. Both the camshaft sensor and crankshaft sensor work (Make AC pulses when the engine is cranked). The ignition relay is also working. Grounds were checked and look good. No rpm detected on tach when cranking the engine. If the tach gets RPM from crankshaft sensor I wonder if this is telling me that its the wiring for the sensor? I am all out of ideas! Please help!
