the crank sensor is located on top of the gearbox and can not be moved.
The bellhousing where the sensor bolts in is in a slightly diffrent position depending on year/model needless to say you need the right flywheel to suit.
The pick up points for the sensor are pegs that are fitted in to the flywheel it's self.(ideally it should have had a new flywheel but the customer had no money)
Regarding checking its got the right flywheel fitted try this
Lock engine at TDC with pin through fly wheel
Remove crank sensor
Remove flywheel cover on bottom of gear box so you can see the back of the flywheel and ring gear teeth
Tipex 1 ring gear tooth against the box
Remove timing pin
Turn engine round slowly clock wise until you see a peg in the middle of crank sensor hole
Now send car back up and look at your mark on ring gear
If the correct flywheel is fitted you will have moved the engine 3 1/2 ring gear tooth's
If the wrong fly wheel is fitted it will be 7 teeth
Luckily to work this out i had another berligo in which i used as a reference
needless to say as previously mentioned first you need to
correct timing
test injector for resistance
make sure the timing solenoid clicks fast when turned on from cold ( it won't do it every time ignition is switched on but when left for a while it should)
