engine troubles and i need help

[JPL]

I came up to college from southern california to the napa valley fine. My engine ran great, but then I go to my car to start it up and it starts up and then dies. Then i go to start it up again and the engine cranks perfectly fine but won't turn over. The next day i go to start it up and it turnsover and start but runs rough and then dies about five second after i start it. What could be the problem. Does it have to do with temperature change from hot to cold? could it be my fuel pump? Battery? Alternator? need some help here. Oh yea and my car is a 90 325i. you expertise is greatly appreciated.

The pump doesnt run until you actually try to crank.

Hook up a pressure gauge to be sure.
