Need some help please!!! 2009 Smart ForTwo Coupe (451.331) L3-1.0L (132.910). (WMEEJ31X39K213799) Auction car. Vehicle came to shop not running. Installed battery, Engine would Crank No Start. Had No Injection Pulse or Coil Signal. Installed Crank Shaft Position Sensor. Then we got Injection Pulse. We did have a RPM Signal of about 475 RPM's when cranking, But No Coil Signal to Coils.
