crank shaft sensor replace 1998 Pontiac Bonneville 3800 motor
well daughters car has been throwing a crank shaft sensor code and been getting harder to start so today got the new one and put it in had to make some more tools to get balancer off but i got it and it went back together very easy.she even called me to let me know it seem to be running a lot better.
Diagnosing GM 3.3L 3300 / 3.8L 3800 Harmonic Balancer Problems
In this video i will show you how to backyard diagnose harmonic balancer failure problems on GM 3300 3.3L, and 3800 3.8L engines. Very simple. The harmonic balancer's are very failure prone on these engines. Enjoy!
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.
No Crank, No Start Diagnosis - EricTheCarGuy
Visit me at http://www.ericthecarguy.com/ Whenever you have a no start condition when attempting to start your vehicle it's important to make the distinction between "no crank, no start" and "crank, no start" situations as they are treated differently. This video covers what I do when confronted with a 'no crank, no start' situation and in this case it's a worst case scenario so be sure to watch till the end.
