Engine + Driveline / Wont Start Fuel Related

I'm sorry, I must be blind. I can't seem to find the sensor. I know it might be a bit much to ask but would anyone happen to have a picture of where it is located? It would be a great help because I am almost certain it is what I need to replace for my car to start.

Engine + Driveline / Crank position sensor location

Sorry for making another thread, but does anyone know where the Crank position sensor is located? I figure I should test it at the sensor and not at the fusebox, so if anyone could tell me it would be greatly appreciated.

Well, do you even know if the pump is running with the car running? It should run on accessory mode. You could start the car and run it, then remove a plug wire, let the engine run a bit longer, and check the plug for fuel. That would be the way I would do it, though there is probably a better way. If the pump is running and seems to hold pressure, I would replace the fuel filter as just a preventative measure, to rule out. Besides that, report back to us with a bit more detail on what is going on and maybe we can figure it out.

The car wont start at all. At the moment I have 12v from an extra battery I have that powers the fuel pump, What I need to know is if there is fuel getting to the cylinders, and if I need the Fuel Pump Relay connected to the pump or will the pump, pump fuel to the engine regardless?

Hey, I recently bought a 91 318is, the car will crank with power but wont start, I went thru this thread http://www.m42club.com/forums/showthread.php?t=5462&highlight=fuel+pump+start

and figured out the wire to the pump has a short so it won't supply power to the pump, I tested the relay it was good, tested the cps from the fuse box to which I believe is good, so i hooked up 12v straight to the pump, started to pump fuel to the engine, but when i try and start it, it seems it still isn't getting fuel, I took a spark plug out, tested it and turned out good, put it back in and when I gave it power it sounded normal so I don't think its the spark plugs, is there a way to check if the engine is getting the fuel I'm pumping to it?
