How to check your crankshaft position sensor on a BMW 740 (e38)
Here I show how to test the crankshaft and camshaft position sensors on a BMW 740i by measuring their coil resistances. You should measure around 500 ohms across the coil pins of the crankshaft position sensor, and roughly 1,000 ohms on the camshaft position sensor coil.
Your E38 will not start unless the DME sees the proper pulse train from the crankshaft position sensor.
The symptoms will be identical to a bad fuel pump.
This is a safety measure to ensure that the fuel being pumped is actually being burned, (inside the cylinders) and not spilling out on the ground after a bad collision, for example.
I should add, as youtuber "Hueristic" pointed out, that this is only for the 95, the Crank position sensor on later models is in a different location near the transmission. You need to get to it from underneath.

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
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

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.

BMW Camshaft Position Sensor Replacement (E39) FCP Euro - #ProjectE39
#ProjectE39 recently has been going through some sensors due to age. The
latest issue involved a faulty intake camshaft position sensor. Some of the
classic symptoms include bad fuel mileage, idling problems, studdering up
hill, stalling, and an overall lack of power.
Thanks to our sponsors at FCP Euro (http://www.fcpeuro.com) we will be able
to get the job done quicker and also give valuable firsthand install

How to clear Check Engine Light and Fault Codes BMW
The method of clearing engine light needs to pass inspection. If you have
check engine light turning on after the car runs for several miles. Park to
nearest Inspection station, and after clearing Check Engine Light, bring in
for inspection. This is good only for car manufactured before 1996 BMW. It
also reset all the fault code BMW.
