I was going to say cold warmup programming on Powerstroke was based on engine oil temp not the other two. But I could be wrong, unless I see it in a book I don't believe even myself.

One guy I know had one of these. After allot of searching there was a small ground wire corroded right at the battery. Seems to me there were quite a few wires on and near the battery.
I found it- cold idle advance is coolant temp & cold ambient protection is intake air temp + coolant temp.

For future reference I can get you a good deal on a NGD DT466 250hp, Just sayin!

After 2001 the PSD's have a glow plug driver, ie electric box for GP's.
Each GP is monitored, will set a code if any malfunction.
Yep, they go to a fast idle after warmup..
I woul;d have bout a Dodge/Cumins if they were not so *&^@ rackety in 2001!

I didn't plug it in last night:
35 deg coolant, oil, intake temp- fired right off: smooth, steady, no misses or stumbles, excellent throttle response. Perfect.
So it seems to only happen if it's been sitting a few days which makes me think 'fuel' like @Birken Vogt asked earlier. BUT- testing it when it wasn't starting showed good voltage, cranking RPM, & ICP (it should set a 335 code if not) & doesn't explain why plug it in for 30min & it goes. Rough, but it goes.
What am I missing here? This is ridiculous. I'm no super-genius but I can usually figure this stuff out. I hope someone will make me have a "Duh!" moment.
I'm going to work on something else for awhile before I do something I'll regret later.

I wonder if the high pressure oil pump is losing its prime?
Requires around 300lbs to start.

Crummy says his ICP is good @ crank....still would like to see the fuel pressure and ICP #'s at cranking / no-start.
Regards, Bob
I'm going to get some solid #'s next time. I'm still kind of scratching my head why plug it in for a bit & it'll start. Like it's trying to light cold on only 1 bank. Since (I think) the pressure sensor is on one of the heads it would seem to indicate it was the other side not getting fuel.
I think I'll start with putting shop air to the high side & see if that shows anything first.
Still starting & running perfect after sitting 24-36 hrs.

Almost sounds like a problem with the IDM, does it have the "3 box" system? Separate IDM from ECM, that may have ended in 99?
I've had all kinds of fits with IDMs on my Econoline, notorious for water intrusion, would loose an entire bank while driving, hard to move 10000+lbs on 4 cylinders! The last one I popped the cover off, sprayed down with fluid film and sealed the cover with RTV, been good ever since.

It's the 1 box. Checked for moisture & resealed everything, no codes, day whatever & still start/run great. Stretching it out between starts- up to 48hrs & still OK.

I see you cut out a rectangle section in the center. Don't forget to include the three little lights in the center. They're required for tails over 80 or 88", can't remember which. I didn't know about the requirement when I first got rolling last year and got a fix-it ticket.
Well, 4 days sitting and it started right up @ 43deg BUT there is just the slightest miss to the ear. Hmmm...where to start looking. I'll put that off till later sometime.
I've had too many things come up to get more work done on it. I did another "weld it yourself" rake/grapple kit for a guy, not something I advertise just word-of-mouth on something I did for myself awhile back. Maybe I should just do those!

I just found out that as of 01/01/2018 you need to be EPA certified to buy bulk (over 2lb) R134a.
What next.
A lot of the reason I got out of cranes was "new rule today! you need a card for this, a certification for that...."
Part of the reason I got out of trucking was "new rule today! you need a card for this, a certification for that, can't go to California, ELD after 12/18/2017, UCR changes, IRP changes, IFTA changes, amber light permit, weight/mile here after this date,..."
Oh yeah, and I got a letter from Licensing too- I've got to bring my original birth certificate in with me this time to renew my CDL. FFS, are you kidding me? I've only had it for 30+ years. Unreal.
I'm getting a little frustrated with this gov't boot on my neck for my own good BS.
