I was certain this was going to be the cause but its showing 85+ psi on diags. I think the good range is 60-75 so its a bit high.

Both HPFP are showing what I think are low numbers but the chance of both failing at the same time I'd thought was slim so I'm still thinking fuel delivery to the HPFP.

I'm still not certain if my car has a fuel filter so going to get under the car and see if I can see one as I'm wondering if I've got a block (Hence higher pressure on the LPFP) than it should be.
