Either my pats system or my fuel pump is not letting my truck start. I am hard of hearing so I can't hear the fuel pump kick on for the 1½ seconds after the ignition is turned on, how do I check them without removing the fuel tank, etc.

Got a truck from the oldest man on earth, 63k, replaced fuel tank, pump, filter, relay, pressure regulator, and injectors, also plugs and wires and battery, map sensor, throttle position sensor, and it still only starts on ether and won't stay running unless I'm putting ether in.

My truck would only fill up 3/4 gas tank then had a hard time to start then one day didn’t start just cranks but no start
