1998 astro van Should an electric fuel pump operate constantly with ignition on?

No, the electric fuel pump in a 1998 Astro van should not operate constantly with the ignition on. It should only run for a few seconds when the ignition is first turned on (to prime the system) and then only while the engine is running.

If your fuel pump is running continuously with the ignition on, there's a problem. This could lead to a drained battery and potential damage to the pump itself. You should have this investigated by a mechanic as soon as possible. The issue could be a faulty fuel pump relay, a wiring problem, or a problem with the PCM (Powertrain Control Module).
