HI there

The code means there is a startability issue. The fact that the fuel pump is losing power after 6 seconds could indicate a security issue. If the immobilizer is set it won't pump fuel. This could also indicate a cam or crank position problem. The computer won't ground the fuel pump relay if there isn't any signal for the cam or crank sensor. It could also mean there is an issue with the fuel pump relay itself.
