Could be the fan clutch as well.
Have you done anything recently to service it, filters, oil, something like that?
Vref is the voltage some of the sensors use as a feed back. Like the ICP, EBP, MAP and a short in one would show. Vref should be right near 5v, 4.8v - 5.0
vref is right at 4.9-5.0 constantly , did nothing to it before the crank no start like I said I have everything it needs to start I'm lost I can find absolutely nothing out of spec ? Will program and check eot and ect on scangauge next
Do you mind posting the actual ECT and EOT values w/ KOEO and cranking ................
as soon as I get those values I will post them as for now I'm leaning towards possible multiple injectors failed pending a buzz test and eot , ect numbers the guy I bought it from said he had replaced 2-3 injectors a year or so ago and the truck sat for quite awhile after

There is a reason I am asking, but if you think it is injectors, then it probably is.
Scan gauge doesn't read codes good. Program an x-gauge for it to read the Diagnostic code count (DTC) and it will give how many codes are stored pretty well, like 2 or 3. Even the little code reader may not do a good job for you. Torque Pro or ForScan does well for codes. If its an injector, you should have a code.

ok so eot and ect both around 42-44 koeo and cranking varies very little truck was plugged in all night I've checked fir codes with an Innova scanner the scangauge also programmed for DTC counts which was 0 also scanned with SCT x4 no pending or current codes it really cranks over today and sounds like its so close to starting chugging whitish black smoke which smells of raw diesel only thing I haven't done yet is buzz test which I'm hoping to get done this week
