BMW 528E GAS PROBLEM

1985 BMW 528e • 300 miles

(1). Cranks over but will not start. I have replaced fuel filter, reference sensor, and speed sensor in that order. If I turn ignition key on and leave it on for 5 minutes the car will start. Therefore, I replaced coil. No change, still will not start unless I leave ignition on for several minutes. Once started, seems to search for cold idle level. (2). While driving engine runs ruff: missing or starve for gas; however, when I give it gas speed does pick up.

When the no start occurs, is there fuel pressure?
