ICP IPR EBP Fuel Pressure all good-- now what

I just bought my first PS it's a 2001 7.3 with 222000 miles on it. Nobody liked my last post and I even put a picture on it. Maybe this one will go better.

I unplugged my EBP. so that is taken care of
I checked my fuel pressure, never dropped below 55 even at WOT, so that is good
I checked all my glow plugs, all good.

I removed disassembled cleaned and re installed my IPR. That is good

My Boost is about 16 WOT, satisfactory

2 new batteries and a nice fast cranking speed.

It runs good and starts good cold. It runs good warm but takes about 3-4 seconds of cranking to get it started when it's hot. which is a few more seconds than I'm happy with.

I tried running it with the ICP unplugged and it runs EXACTLY the same as when it's plugged in. But I have NO SES light.

Any ideas?

Thanks

when hot, cranking, does pressure gauge rise as fast as when cold?

shoot.... this looks like my first opportunity to sound dumb. Are you talking about my fuel pressure? If so I let the electric pump get to 60 before I even start cranking.
I'm going to assume that you are really asking about the High pressure Oil. In which case I'm sad to say I have no way to monitor that. My OBDII scanner won't work on my truck.

Oil pressure comes up the same, warm and cold. I'm getting new oil today, maybe that will help

If you use 15-40. I switched to rotella t6 synthetic and it improved start time to at least half if not better.

A day late and and a dollar (or sixty) short. I just got Rotella 15w 40. Sounds like I'm up for another 5000 miles of long crank starts. Is this t6 a popular oil for Powerstrokes? Maybe I should have done my homework.

How much does 15 quarts of t6 go for? And how many miles do you go before changing?

Anyone else have stories of success with this oil?

You need to have get an actual reading off the ICP to determine what the HPO system is doing during start up.

Maybe I should start a new thread, but I like the responses I'm getting here.
I tried testing my glowplug relay when the engine was up to temp. They didn't go on at all. Not even for a second. I was under the assumption that they were always supposed to turn on for start up, even if for a mere 10 seconds.

Tested with engine cold and the worked fine.

How is this system supposed to operate?
