I have a Vauxhall Astra H (2007) 1.7 cdti cranking but not firing up - no error codes. A bit more info below -
Crank sensor replaced last week
MAP Sensor replaced 2 weeks ago
Battery good
This weekend just gone cleaned EGR Valve and pipe (same issue before clean) - EGR Valve closed
Also, last week had some look to replace the starter and crank sensor but he couldn’t get the starter off so just sensor replaced. We started the car 2 - 3 times and it fired up ok.
Starter motor seems fine according the AA who I called to look at the car.
Unfortunately the person who replaced the crank sensor though it would be a good idea to check the injectors so he decided to proceed and take apart the 4th injector but don’t think he knew what he was doing so it was put back together and connected up.
This is when the car just refused to fire up, just keeps cranking. There’s fuel coming through the the high pressure hose and top of the injectors but still not firing up.

Any ideas what this could be?
