I've had a lbz before that would not start below 0 at all, unless plugged in

Was injectors that was bad in it

Think I still have issues from new injectors even though they are new in a bosch box

Lil' late to the party here but do a compression test, pretty much the only times I've seen rates that high is a mechanical issue.

Was thinking along that lines going to lift valve cover over 1-7 side a see if any issues may have bent push rods on 7. A compression check is done thru glowplugs??
