We've got a problem with engine doesn't start. There are accident fireing and claps into exaust and intake like a jumped chain but the timing marks are ok. Engine has 2 CKP sensors. One on the drivebelt pulley(hi-res) and other in the middle of the block near knock sensor(lo-res). Both sensors are working.Signal from the lo-res sensor goes to the ignition control module, according to the Mitchell scheme through the amplifier in ignition control module to the ECU. So anyone knows what signal waveform should be from the amp in the ICM?
