Fuses/relays in the engine bay ?

Negative side of the fuel injectors goes straight to the ECU, so if they're not firing it's because the ECU isn't happy.

Positive side is fed from the main relay (one of the purple ones in the engine bay fuse box).

Is there fuel pressure?

sounds like youve got a dodgy crank sensor
