Long crank to start time, more so when warm. 1999 7.3

My truck takes a few seconds longer than normal to fire over. I bought it with 287k miles and ive just hit 289k on it. Its been like this since i bought it. Seems to run decent, no hesitation, skipping, missing, ect. I have since serviced all fluids and filters, changed cps, ipr, replaced leaky oil line that goes from hpop to cyl head (driver side). So now it runs decent, no leaks, just takes longer than it should to crank over, oddly more so when warm. What could be the deal here? Im starting to think/hope that the starter is just getting wore out, doesnt seem to spin nearly as fast as it should. Batterys/charging system good. 3/99 eng build date.

Come on idiots. I know not all 7.3's start as soon as you touch the keys. Just because I drive a Chevy doesn't mean I don't like my 7.3.

Mine does the same thing it seems when my truck is warm. I only have 33k miles on my truck so I doubt it's my starter. Tuned in to see what other people have to say.

Almost 300K; HPOP may be tired. Have access to AutoEnginuity or got gauges to provide any sort of numbers for HPOP,fuel pressure, or oil pressure? Could be any number of things.

Ill hook up my buddies snap on scanner and see what i come up with. Thanks. What are symptoms of a weak hpop. My truck runs well but power wise its a slow dog even for a regular cab. Im probably going to chip it because i almost have to floor it to get onto the freeway. Maybe icp sensor going?

Yeah, I was going to say look at your ICP pressures to tell if you HPOP is old & tired. Usually when an ICP goes out you can tell because there will be oil in the sensor connector. Also how your ICP pressure correlates to Duty Cycle % will tell you about your HPOP's condition. Since that is what drives your injectors that could be it. Fuel pressure would be good to know as well. Do you have any boost leaks that you know of? Any soot on the firewall near the up pipes?

I dont think my up pipes are leaking. The turbo charger is only a year and a half old and seems to build and hold boost just fine. But ill double check for sure. Fuel economy seems to be fine. And also, I mean if i literally floor it, the truck gets up and goes, but otherwise seems on the slow side and usually holds to 2500 or so rpm before shifting. Maybe im just too used to driving newer trucks.

When my truck is warm, sometimes it takes maybe 2 seconds to start, and sometimes it starts almost as soon as I turn the key, so I really have no idea.
