It finally fires up after about 20 seconds of this. Very frustrating. Any ideas?

My X5 is having quite similar problem except it does it in the morning. Cold morning starts just cranks the engine; letting it rest for awhile fires up the engine. Did this for 2 days, 3rd day did not start at all so i had it towed to dealer. Fuel pump was replaced.

Now, after 3 days having hard start again on cold mornings. Its starts after 3 attempts, i'm thinking does the fuel line need bleeding after fuel pump replacement ? I know its done with diesel but what about gas engine ?

Looking for advice before i call dealer again, more $$$ to spend on this.
