My boys ram truck is having fuel probs. He's replaced fuel pump and filter and still not getting fuel. Think it's a 98.

Error codes?

 

Fuel pressure at the rail with the key cycled on?

He's not here right now. He claims you do not hear the pump come on.  I'll get codes later.

Codes might give a clue to why the pump isn't coming on. As for the fuel pump it should have a fuel pump relay in the PDC under the hood. ASD relay might shut down something because of another issue. I'm not saying ASD is the cause directly but the PCM sense something and shut it all down. Hence looking for codes.
