Car delaying starting after fuel pump was put in

I just had a new fuel pump installed a couple weeks ago. Since then, when I would try to start the car I have to crank it at least 3 times before the car will start. It would crank, just not start.

And the past 2 days when I go to try and start it after it has been sitting for a little time, it won't start.I have to sit there for about 10 minutes before it will actually start.

And now I just went out to start it and it just cranks but won't start.I have sat out there for 30 minutes and it still has not started this time. I drove it earlier this morning and it has ony been sitting about 4 hours. But now won't start. This morning it took it about 10 minutes to start but it eventually did. But not now.

Any ideas?

Also since I got the new fuel pump put in when I go get gas, the gas pump kicks off every couple of seconds and fuel spurts back out onto the ground. It takes about 10 minutes to put $20 worth of gas in because it clicks off every couple seconds and makes a gurgling sound. Don't know if that has anything to do with it either.

Any help would be greatly appreciated.
