new crank sensor fitted engine turns over but won't firer up ?

Any other faults before the change

Does attempt to fire

Try easy start..if it fires up atall then it's a fuel fault

Was it running prior to changing the crank sensor?

Have you read the codes to look for faults?

None does attempt to run with a sniff of easy start

Have you tried priming it until  bulb is solid

Ok, so it ran fine before you changed the crank sensor. Could be you've not pushed the sensor in far enough. So slacken it off, push it right down till it hits the flywheel then back it off 1 mm or so. Does it fire up now?

p.s. why did you change it?

the sensor doesn't push in. but it might have a mm or 2 movement will the crank need to be top dead centre before fitting the crank sensor
