“… It does start on the second attempt and if I shut down then immediately restart it does. BUT leave it for a while it wont on the first attempt…”

Try turning the ignition on an off three or four times (hopefully hearing the pump prime a couple seconds each time), then crank it. It sounds like the fuel may be draining back, leaving the injector rail void of fuel to the point that a single priming shot isn’t enough. A fuel pressure gauge attached to the fuel rail will reveal how fast the pressure bleeds down. I can’t recall what sort of check valve the Regina system utilizes, if any, to prevent rapid drain-back.
