Where did you undo the injectors from.was it pipe/injector or pipe/Fm unit.If you undo the pipe from the fuel meet unit you should get some fuel out if you crank it.Be careful though.Is your pump working ok.When you turn the ignition on is it whirring and then stopping?lets know m8.I aint an expert but I had probs like that and my m8 sorted it out for me.I will try and remember.
