No starting after crankshaft sensor replacement ?

[s10blades]

I Replaced the crankshaft sensor on my e85 2.5
The car no longer starts , just turns over
The car was starting fine and running ok but had error codes pointing to the sensor , this was the reason for replacement
I have tried putting the old one back in and it’s still the same
Any ideas please? Do I need to do anything specific when replacing these sensors? Thought it was just a case of plug in a new one and that’s it ?

Thanks

It’s possible there’s a broken wire at the connector.
