V70 Crankshaft Position Sensor Problems

I have same exact issue on my xc90 t6.
Replaced sensor replaced bracket.
Initially had read about starter interference from worn brushes.
That solved the issue for about 2 weeks now back to hot start issue and reduced engine performance any time above 3k.
Maybe I'll check the bracket again....

Once again bracket seemed to resolve issue. Damn that thing is finicky.

And hard start returned!! No jumpy tach no codes whatsoever.
About to make it an appt with a tree...
New starter, new cpk, new bracket, new battery, new coils, new plugs, added grounds cleaned grounds, shielded wiring moved wiring away starter/sensor harness.
Semi long cranks when cold excessive cranking to start hot...
Maybe it doesn't like this db electronics starter but was new not refurb and they have great reviews.
Turns fast has gpod fp at rail..

What’s the measured fuel pressure at the rail?
