Check the fuse in the underhood fusebox... shld say fuse 22 or fuel pp

Also this fuse box design has a bad problem with contact issues.. if u look at the underhood fusebox you should see 4 silver bolts in with the fuses holding it down... make sure these are not loose

Without a testlight, volt meter and actually being with the car to do tests its hard to say... need to verify on pin 85/86 that the pcm is supplying B+ when the key is first turned... its completely normal for fuel pump to lose power after a second or 2 after turning key on
