The fuel pump relay is a good first place to look. The PCM relay is the same shape and size and can also be an issue. However, you may have a fuel pump electrical problem causing it to not activate. Have a fuel pressure test performed.

However, before you do that - check the fuel pump emergency shut off (inertia) switch in the trunk - just on the off chance that it is tripped.
