Classic symptoms of a failing fuel pump. Check wiring and connectors before replacing pump. It’s always best to confirm that pump isn’t operating when no start occurrs though. ---

Agreed, classic failing fuel pump. They were notoriously bad during this time period. Plan on about $700 for the part and labor. They’ll have to drop the fuel tank to change the pump.

Yup, I used to carry a 5# sledge hammer and a 2X4 to bang on my gas tank to get the pump running again.
