Fuel pump squeal....

[Mark_123]

OK, so I've never really had to turn my truck on and off and on without starting before getting my Gryphon. This may have been happening since I bought the truck, so I just wanted some opinions. When I turn my key to "on" without starting, I hear the fuel pump power up normally. When the pump stops (after just a second or two), it makes a squeal like sound as it stops. Is this normal??? Are there any particular readings I should monitor in my Gryphon (Fuel Rail Pressure) to be sure the pump is OK? Like I said, this may have been here since day 1, I just normally didn't turn my key to "on" and wait to listen for it. Thanks for any opinion.
