just need to know where the crank angle sensor is located? will I have to jack the car up as I think it is under the engine?

Strange terminology. I think you mean the crank sensor, aka TDC sensor, aka rev sensor.

It's at about 3 o clock to the alternator pulley (from which it picks up the signal) on the timing side of the engine.

im with fingers here

look at these 3 images, you'll never see such a clean engine!
