Replaced fuel pump- now won't start

Replaced the fuel pump and filter on 2001 Jimmy. It ran just find that day- then the next morning will not start. Sounds like normal- battery/starter seem fine. Any ideas?

Can you hear it prime on key on if not check all the plugs to make sure there tight. Give it a jump start if that works may have a dead cell in the battery.

ave you checked fuse?
If you can hear fuel pump run or jumper it and get it to run give us the fuel pressure readings.
