Point 1.
A PP3 battery is nowehere near big enough to run the fuel pumps -
either of them!
Point 2.
It'll never run now! Put the coil conections back
AS THEY WERE!!!
Just hope you haven't caused any damage to the ignition amp by connecting the coil the wrong way.
Add 4L of methylated spirits to the petrol in the tank, put the coil connections back as they were get a fully charged car battery (NOT a PP3
) and try it. Might take some time to get the meths through but that will get rid of any condensation in the tank.
