What year, engine and gearbox is the car? as members will need to know to look up things. If you can post the RPO number found on the tyre pressure sticker it may help. Good luck.

Have you checked if the key is being recognised by the immobiliser ? Leave it in the ignition and open the driver's door - most cars give a warning message but if it is not recognised you may not get one.

Did you remove the flywheel as part of the rebuild as the crank sensor ring is mounted behind it, you would not be the first person to forget to refit it or plug sensor in as its tucked down at the rear or the engine

Can you seen engine RPM on live data?
Do you know if you are getting a switching signal at the injectors?
Was it running immediately before the engine rebuild?
