03 S60 Hard starts

Hi everyone, need some help. Car needs a lot of cranking to start but once started, runs excellent. Fuel filter been changed, fuel pressure is good -35 psi, new plugs. Was told in other forums to replace cam sensor or fuel pressure sensor but still skeptical to do so. d(st)ealer wants $815 to run their diagnotic machine on my engine but said its too much. No DTCs or CEL right now. Car has 82K miles on it, 2.3L T5. I'm afraid I might ruin the starter or something else w/ those long cranks. Does anybody have any idea what to check out. Thanks

Maybe this applies to you:
