new fuel pump just stopped while driving!

so i ordered a fuel pump from summit and installed it. probably driving the car atleast 30, 40 miles just driving now and then in the neighborhood and all of a sudden the car dies, i turn the ignition off and on and i hear no fuel pump whine. installing this fuel pump was a pain :( and i hope not to install another. what else could be a problem with this?
 
new spark plugs and injectors they are good. tested those. i was looking up on some research and it was saying something about the eec relay by the computer. think that could be the problem to? fuel pump relay is good. i'll have to drive the car some more to see if it will happen again.
