Hello, 

Thank you for writing in. Considering that you just replaced the fuel pump, there could be issues with the installation. The fact that the vehicle is cranking but not starting also suggests that it is not getting fuel or spark at the right time or in the right amount. You can test the fuel pressure at the engine to see if the pump is providing the fuel that the engine needs. This is the most direct way to see if fuel is actually getting to the engine and verify your fuel pump install. It may also be an electrical issue, but you will want to rule out the fuel pump first considering the recent repair. Good luck!
