Many possibilities from the main relay for the ignition (2/23 in the main relay terminal), the ignition switch, a camshaft position sensor gone bad or bad connection, PNP switch, ignition coils themselves- bad leads from your battery (corrosion, bad grounding, etc.), bad MAP sensor, MAF sensor, ECM, Immobiler system, the list goes on. Have you checked your diagnostic trouble codes?

Couple of questions--do the injectors cycle? (If you have a noid light, hook it up to #1 cylinder's injector and see if it flashes in time with the engine turning cover.) Any messages on the DIM about immobilizer? Also, is this a North American V70 or from another region?

You checked the impulse sensor- have you checked the camshaft position sensor? This will also cause a no-start condition. A diagram for it's location is in this thread: https://www.matthewsvolvosite.com/forums ... =9&t=18416
