Engine wont start

It's not going to fire with no gas. Try priming the fuel pump to get flow started.

the placement of an electric fuel pump is crucial- they should be as close to the fuel tank as possible- they will PUSH better than PULL- is that where you mounted yours? also check to make sure that any new hoses aren't bent too badly to be crimped- all hoses and lines must be free flowing or the pump will work too hard- this is a difficult job, to mount a custom installation properly
