VAUXHALL ANTARA 2.0 CDTi CRANK NO START! 

sandy i would remove the dpf and try starting it must be blocked solid with that amount of back pressure , check low pressure fuel supply also check the regulation valve is tight enough if its not it wont seal and fuel will return back to the tank should be 65 nm (got that tip from martin wainwright) lastly remove the leak off pipes get someone to crank it and check for any excess leak back in case any injector seals have failed .

Injector leak off, ground the pressure reg and see if it holds/builds pressure like franks video

1100mbar dpf pressure on cranking wow !!!!!!

Just for testing purposes you can disconect the fuel rail pressure sensor and ecu will use a default value just to see if it will run on some systems

my antara frequently when turning the key all lights come on but nothing happens. If i hear the pump starting at the back of the car it starts, if not, nothing. Anyone any ideas? its an intermittent fault, feels like immoboliser but truthfully no idea.

Has someone stuck a potato in the exhaust lol

Hi SandyAppreciate if you know and could recommend a scan tool with live data around £500. Thank you.
