This is completely abnormal.  Either the ECU is misbehaving or some foolish
person has rewired the fuel pump to run directly from the key.  That's
extremely dangerous because the fuel pump needs to stop when the engine
does in an accident.

Normal operation is a couple seconds or so when the ECU boots, and then
during cranking and any time the ECU is getting timing pulses from the
distributor**
