What do you need to know about crankshaft position?
Make certain that the Battery is in a fully charged condition. You’ll need to test for spark at all cylinders to be certain that there’s no Spark present at all. If Spark is present, the Crankshaft Position is working properly. Test for Fuel Injector Pulse, although depending on the fuel system design this is not always possible.
How can I test my crankshaft without rpm data?
So, if you have no live Data, you won’t know/see if there is an RPM signal on the Scan Tool display screen (in case you didn’t know, the Scan Tool displays the RPM’s from info from the (CKP) Sensor). Therefore, knowing how to test them with a multimeter (or an LED or an oscilloscope or whatever) independent of a Scan Tool becomes very important.
