I picked up a 1988 944 CE 3 months ago, with a list of items not working.  I repaired most of them.   But I added antifrez and bleed the air out with bleeder open and the cap off with heat on high.

temp went up on gauge two lines but no hot air out of vents, no radiator fan on , let it run for 20 mins.  Then I closed the bleeder and put the cap on. The car died out and had trouble restarting and when it did start it ran very rough. Is the thermostat  not opening?

Possibly.  Pull it and test it.

When the car came up to temp the DME relay would over heat and fail and the fuel pump would stop running . Installed new DME relay and it runs like a top now.
