After crashing my ninja 300 the fuel injectors aren’t pulsing anymore. They have a solid 12 volts to the hot wire but the ground one has no signal. The fuel pump works and the bike turns over and will start with starting fluid.
Accident damage was front end such as forks and radiator

The service manual unfortunately doesn't go into how the engine gets shut off when the vehicle down sensor is tripped but I suspect it shuts the fuel pump off. This would make sense as the main reason for the sensor is to stop fuel from being sprayed from a damaged hose.
That being said the manual does, in good detail, describe how to test the vehicle down sensor. It appears that, when working correctly, the sensor should reset itself when upright again. It's possible yours is pushed at an angle though.

Are you sure there gas in it? No offence but I'm a mechanic and have seen it quite a few times over the years

Ok. Well I would imagine if the vehicle down sensor were tripped the fuel pump wouldn't run but I could be wrong. All you need is a multimeter to test it though. I'd do that first since it's easy to do then go from there.
