I added a blue light on the instrument panel to let me know the fuel pump is on.

 

I need this. I have an alert set on my Ipad for 60 sec after takeoff, but the pump still gets left on. Did you just come from the switch with a simple indicator light?

Yes:

I have a climbout checklist that includes the boost pump, gear up, flaps up, etc.   It's handier than one would hope.

Later models have a blue “BOOST PUMP” indication in the annunciatior panel.

BTW, not all Mooneys use the fuel pump on take off.   It is not in the checklist for my M20K.

 

In fact there is a Takeoff checklist to confirm that the boost pump is Off/

This!! No need for hardware solutions for software problems...

Although the early Mooney electric boost pumps burned out pretty quickly when left on, these days once overhauled they’re all rated for continuous duty. Thus it shouldn’t be the problem or concern it was years ago.

Yes, the Continental fuel injection system is fundamentally different from the Lycoming in theory of operation.

its important to follow these steps upon learning you have a bad electric pump on the ground -
 

Step one remove key from switch

step 2 remove all occupants 

step 3 walk to car

step 4 drive wherever it was your going

You will get fuel pressure just cranking it. I rarely use the boost pump to start my plane.

If you need to fly it somewhere for maintenance, you will need a ferry permit to do it legally.

Probably referring to priming it with the electric boost pump.

Yes. I run the electric pump until fuel pressure stabilizes, then turn it off and crank. Was taught this at a MAPA PPP just a few months after purchasing my Mooney.

Boost pump off except for priming and emergencies is common (although not universal)  the big Continentals. It's true for the Bonanzas as well. Not true for the SR22.

For my 1965 M20E, start checklist, you turn on the electric fuel pump, push mixture in for 5-7 seconds to get fuel in the lines/cylinder, turn it off, pull out mixture and then start...
