V-10, She cranks good, but she's a No Start

2001 V-10 cranks good but no start. That's the intermittent problem a friend is having. The next morning it usually starts.....runs normal.
Could a bad fuel pump act like that ? Or are we talking a bad connection to either the pump or the coils ?
He did not check for spark,.....I think he is afraid of it. So am I !

Any ideas >

    I would tend to guess not the coils, since it seems rather unlikely that ten coils would all be intermittent in unison. The engine should start and run (albeit roughly) with a coil not working.

    Fuel pump or associated parts seems like a good guess to me. It might also be a friend of Stewart Little or Chip & Dale snacking on the wiring somewhere.

    Yes, it could be the fuel pump relay. If like many, it charges the fuel system, then shuts off.
    You might also check for OBD codes. It may set a code but not turn on the engine check light.
