try a leak back test on the injectors they should all be within a few ml of each other.

If you have diagnostics with live read out - I'd monitor the fuel rail pressure - start monitoring before you start cranking, see if the pressure builds quickly or slowly and if that's relevant to when the engine starts.

In normal circumstances, metered fuel pressure should be reached within 1 second of normal cranking.

If slow pressure build, then leak back test as suggested above.

Thanks again. Going to do a rail pressure check while cranking as soon as I can. Think there might be a patch of dampness on the fuel filter housing. I'm wondering if I have damaged the in connection when I disconnected the pipe to help drain the tank.
Then leak test of injectors.
