crank no start

[Dieselcraft]

i came home and cleaned the garage parked my truck in garage
went inside watched a movie blah blah
me and my woman were going to go on a hot date
crank no start.
my oil guage goes half way so i have low oil psi
no dtc so im like f-IT
we stop by my work i grab the IDS
go to date come home i run data log i find no cmp and ficm sync
im scraching my head
long story short im looking at my left battery the cables are clean im like what the hell ill pull the bat to inspect pcm connectors
keep in mind i left the key on
i loosen the 8mms i take - off and pick up + and the fuel pump kicks on im like WTF???
i remove the pos wire and its clean so i scuff it up and put it all together
run data log wa la i have SYNC

weired how some problems occur

so i found the problem or the + wire from the harness has a open
my truck now starts thats all what matters i will check my Resistance later since i dont have my fluke at home

im ready to purchace my own IDS
ohh by the way im running stock fuel pump at the time since my air dog took a CHIT

FWIW mine did that sometimes too. happens very rarely. I turn the key off and back on again and it goes away.
