I have an S80 diesel 2011 automatic model. On three occasions would not start. Turns over but will not start. Does not seem to register any fuel on the gauge. No faults come up on volvos system. RAC and volvo assist could not find a fault. Got it started but no one knows how. Maybe disconnecting battery or resetting software or this time just by moving the car it started.

Thank you. Would it be an intermittent problem. A couple of times they disconnected the battery and that seemed to start it but one time after taking it to the garage on a recovery truck it seemed to start.

The garage about to take diesel tank out to check fuel which sounds expensive so looking at all my options, No faults showing up

It can be problem with fuel tank if it got better when you lift up on tow truck then fuel pump moves around
