My 90 IDI N/A starts on one or two engine revolutions, cold or hot weather. WHY, because the fuel system is kept up to par, no air intrusion, good lift pump, the batteries are 4 years old, battery cables and connections are kept in good condition for plenty of cranking power, a functioning glow plug system, starter is original as far as I know, not wore out from long cranking. The E4OD transmission was rebuilt buy me, blew the cooler hose, neglected to tighten a hose clamp after replacing it. Shifts just great automatically, I can even shift it like a manual tranny

, how about that. It does have a 2007 Promar remanufactured engine, PO never used the coolant SCA, it cavitated #6 cyl.
The 92 runs just as good, and it's got an 88 engine in it, PO burn't up the original engine at 129K miles, ran it with no coolant in it, gotta rebuild the E4OD in it, PO ran it hot and leaks fluid. Now when rebuilding the tranny, all updates are installed along with a tugger kit for towing.
I drive the 99.5 most of the time because of the Crew Cab, it's stock with 180K on it. The 4R100 tranny was rebuilt at 168K, my fault, torque convertor nuts came loose and tore open the case. No trouble starting, cold or hot weather. I've towed some awful heavy loads with it, like 22,500.
DIESEL's forever.

3200 oil psi to start if I remember right
Not correct, takes only 500 PSI to start. But, when running it can develop up to 18,000 PSI to fire the injectors.
My rambling on is done.
