2005 Chev. Silverado... yesterday showed a false engine

Customer Question

2005 Chev. Silverado... yesterday showed a false engine overheat.. with a temp. gauge pegged at 270... My shift indicator stays in PARK although the shifter lever is moved to neutral... lastly, engine will not crank.. just makes a click noise....
JA: The mechanics have tons of experience in that area. Do you happen to have the code?
Customer: no. sorry
JA: Not a problem. You can work with the GM Mechanic to figure that out. Are you hoping to fix this yourself?
Customer: would like to.. if possible.
JA: Is there anything else important you think the GM Mechanic should know about your GM?
Customer: indicator for reduced power now is displayed
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the GM Mechanic about your situation and then connect you two.

Hello, my name is***** it make a single click or multiple clicks ? Thanks.

Customer: replied 1 year ago.
I hear maybe two clicks... very close together. The truck stopped while idling.. then no restart

Had the truck towed.. continued to show it was hot even after several hours... disconnected negative battery terminal, and temperature sensor, waited and then reconnected.... Engine Overheat was gone as well as the high temperature reading on the gauge...

Do you have a multi meter to do some testing? Thanks.

Customer: replied 1 year ago.
I do but I am not with the truck now.. at work... truck at home... I may be able to get out of work early

Ok, start by testing battery voltage. Monitor voltage while trying to start, if it drops below 11v that means battery needs to be charged or replaced. Let me know how test goes, thanks.
