No Start, No Spark, No Injector Pulse (faulty crank sensor)
No Start No Spark Case Study 1997 Lincoln Continental 4.6 How to test a VR type crank sensor. (VRS) This is a great video if you are looking for tips on finding direction on any no spark problem.

Crank Sensor Quick Fix
GET SOFTWARE HERE: http://www.autodiagnosticsandpublishing.com/Software_Catalog.html Crank Sensor Quick-Fix There are two types of crank sensors, and two types of tests, the 2 and 3 wire sensors. Here are the flash points for the crank sensor testing. 1) The 2 wire crank sensor generates a voltage, and is quick tested with a test light. 2) To test the two wire sensor, disconnect the crank sensor, ignition key on, hook the test light to battery power, and tap at each crank sensor terminal repeatedly. A spark click and injector pulse should be seen. 3) The 3 wire sensor has its own circuit, with 5 to 8 volt power, ground, and signal wires. Identify the signal wire using volt meter or diagram. 4) Take the test light and connect to battery ground. With key on, disconnect crank sensor, and repeatedly tap on the signal wire. You should hear a spark click and injector noid pulse. These are to test the ECM crank sensor circuit response. On both tests, you should see a spark click and injector pulse. Crank sensor is the main input to the ECM. If ECM working, then the crank is the only other issue. There are other ways to test, but involve an oscilloscope and more complex. This concludes the cranks sensor Quick-Fix.
Camshaft Position Sensor P0340 Testing and Replacement HD
Click Here to Subscribe! http://youtube.com/carsntoys Website: http://carsntoys.net Today we're testing the camshaft position sensor, along with its harness connector. The sensor consists of a permanent magnet, core and coil. When the engine is running, the gap between the sensor and cam sprocket will periodically change. This generates a voltage and sends the information to the ECM. Code P0340 could be generated by the following reasons: - Harness or connectors is open or shorted. - Camshaft position sensor - Starter motor / starting system circuit.
