The Intank Pump seems fine - what a wonder if replaced recently
"Seems Fine" is not good enough - You really need to be looking at Pressure and Flow at the back of the HP Pump.
The fact that it is "NEW" is more reason to check it properly. Chances are the previous garage took off a good one and replaced it with a cheap nasty aftermarket.
I am sure I have seen "New" fuel pumps looking better than that on an amp clamp trace. Then the fact that it is pulling above 20 amps to get it going, Is it bad or is there a restriction it is fighting ??
And there the current is dropping off to zero on cranking with (some) voltage present
Is this demand controlled with PWM on the Earth side ??
