Not sure how I missed this, ran out to the car with my laptop from bed...
Can confirn my INPA was all kinds of messed up, I ran the fuel pump test and the sound came from the correct location unlike my INPA copy that activates the SMG pump seemingly. (noise comes from the hood)
After I ran the pump test I tried to start the car and it fired first go so I'm confident my Hella pump checkvalve is faulty.
Many thanks.
