Further to my last thread the car has now decided not to start at all. The only thing I deliberately changed was the MAP sensor for brand new, even with the MAP unplugged it won't try and start so I don't think it is that. The fuel pump primes and there is fuel getting up to the rail, also getting spark so think that rules out crank sensor, double relay or immobiliser issues. One thing I have noticed is that when cranking injectors 1 and 4 are clicking away like crazy whilst 2 and 3 click once every 3-4 seconds only which doesn't sound right at all. Getting seriously wound up with it now, anyone got any ideas?

It will occasionally try and fire but it's not a very convincing effort. It is supercharged and therefore has a new ECU chip which I have checked and am fairly certain is seated correctly, ECU light illuminates on the dash which I know it doesn't if chip is not in properly.
