This may be a silly question. If you were hand proping it because the
battery was dead, was there enough battery for the fuel pump and
injectors to work?

Hey guys,

I tried hand-propping a 172SP yesterday, without success. I don't have
experience of hand-propping (I was at the controls), but the guy
throwing the prop did.

I understand that it's tricky with a fuel-injected engine (which the
172SP has). Anyone have any tips on how to do it?

Bingo! Tina, you get an A. I bet there's not enough pressure on the
injectors to spray the fuel.

The electric fuel pump is turned off before you engage the starter in
a normal start.
