i have a good spark and fuel but it won't fire, not sure if this is relevant but i bought a draper code reader and plugged it in but it doesn't flash or light up at all, but i've checked all the wiring and there is power where there should be, the fuel pump primes, all the sensors click when ignition goes on, but no start or power at the fault code reader, any ideas, i'm baffled??

 

not sure about the reader but the not starting could be something like the crankshaft position sensor ( or somat like that). check that all sensors and things like that are connected and if they are check the terminals are not corroded

yeah i've checked all that, the only thing i havn't yet checked is the injectors, i've checked the wiring and its definately pulsing and i have pressure at the rail but i havn't physically taken the injectors out and checked for fuel but i was thinking it would be unlikely for all 4 injectors to fail at the same time
