I just got my car out of storage and it run fine. After 1/2 minute when I shut the engine off it started making a noise coming from MPI when I turn the switch on the noise goes away. Does anybody know what could it be?

Good news. I replaced the ECU and noise went away, problem is solved.… There might be something going on inside the ECU but I don’t have skills to repair that. At this point I just experienced that replacing the ECU took care of the noise.
