We had the same on our build last year; plenty of fuel, engine turning over, immobiliser off, inertia switch working, but no noise from the fuel pump (you'll know it when you hear it, just a brief whirring from the boot when you turn the ignition on). After much checking, double checking, calls to Derek, etc. I called out an auto electrician who diagnosed a bent pin in the plug connecting to the fuel pump. Bingo! Pin was straightened and she started immediately, while he backed off quickly as the two of us danced around the car like a couple of loonies!
