    Hi Keith Brown, I want to help you with your question, but I need more information from you. Can you please add details in the comment box?

    Is there is "click" noise?

    If so, do you hear any cranking sound?

Sounds like the timing belt broke. Unfortunately this vehicle was not equiped with no contact valves so if that is the case you will need to have the engine and Head rebuilt. If the crank position sensor can't sense the position of the crank it should shutdown the electrical to keep you from damaging your engine.

SOURCE: Where is the Crank Sensor '99 BMW 523i E39 Auto

are you sure you need the crankshaft position sensor changed. it is at the back of the engine i believe, but.....
check for a wet ecu first... read the note on e36...

the ecu compartment is under the windshield on the passenger side on E36

you gain acess to it under the hood....
this compartment gets wet, the ecu lays on a flat surface in that
compartment.

the bottom side of the circuit board gets wet and starts corrosion.

remove the ecu, take the bottom plate off, clean the bottom of the circuit
board with alcohol and a soft tooth brush.

you should be able to see the signs of corrosion or conductive build up.

this gunk bridges solder points doing all sort s of wierd things to your
car, including false sensor readings from asc/abs controllers and other
sensors....

all the way to engine failure and worst case burnt and shorted wiring
harness.

I'm on my 3rd ecu, took me and the repair boys a few years to figure this
one out.

BTW: i would get that ecu mounted above that flat surface, use some sort
of standoff to raise it so that it is not laying in the wet.

My 2000 Bonneville did the exact same thing. It's the mass flow air sensor I'm almost 100% sure this is what your problem is.

Why wont my 2003 bmw start


No gas, weak battery, crankshaft or camshaft sensor is bad, fuel pump bad, fuel pump relay or fuse is bad, haven't pushed clutch down far enough(rug caught underneath), fuel filter clogged, ignition coils bad. You need to give a hint as to what you have tried. Does it crank but not start? Does it simply click(starter) and not crank?

Where is crankshaft position sensor located 1996 gmc sierra 1500


The crankshaft position sensor is located on the right-side (passenger side) of the engine. At the rear of the engine, behind the starter. You need to remove the starter to remove the crank sensor. Remember to disconnect the battery first. The starter can short against the cross member.

My 97 520i bmw wont start it fires some times but wont start is it a petrol problem


If it fires only occasionally, my first suspect would be the crank position sensor (aka pulse generator). Should be on the front of the engine mounted very near the toothed wheel on the crankshaft,
You should check for fuel pressure at the fuel rail while you are cranking to see if it is a fuel delivery problem.
