325e Starting Issue

I recently acquired a e30 325e in pretty good condition externally but it seems to have a starting issue. When I go to start it there seems to be excessive cranking to get it going, some times it will go other times it wont. I tried today twice, at 10 o'clock it wouldn't go but at noon it started right up. The previous owner had taken it to a few shops to get it checked out, try to get a list of everything they did. He said they cleaned the injectors and throttle body, checked cold start injector and new plugs. They said the car seems to be getting to much gas vs not enough, once the car runs it runs fine and won't die out but on some hills it seems to lug a bit and hard to pick up speed.

I pulled the vacuum line off the fpr and that didn't seem to aid in starting, switched the O2 relay and fuel pump relay no change at all. Wondering if fuel pump may be getting weak or fpr?
