Voltage when the car is running and the headlights off should be around 13.5+ volts. With the headlights on, less. With the engine off, more like 12.8 with the headlights off. With the engine and headlights off....12.6V+. A battery not reading well in excess of 12V with the engine and headlights off should be replaced.

Clean electrical terminals are essential. There is virtually nothing you can do to your car more important than cleaning and/or wiggling all the electrical terminals. Best practice is to clean with vinegar and coat with Dow Corning 111 or 112.

I have heard of fuel pumps failing. Even while the car is running. The advice those drivers would offer is to just replace the FP. Before being stranded.

So yeah, that is my advice. Replace the FP, clean the terminals and make sure your battery is doing its job. Problem(s) solved.
