Hello yall.
My friend asked for my help with his megasquirt after switching to a mpxh6400a map.
It was mounted on a adapter board.
I found the problem and unfortunately he soldered it wrong way (mounted on top)
So gnd got the +5.
When he hooked it up all it did was run fuel pump on.
I turned it correctly but it's not working now either.
But it's not running the pump anymore.
Where to start with the search for fault?
He tried to connect to it with no success.
Thanks
Cheers

Check the MAP sensor output voltage.
