Best place to start is to get the fuel presure tested with a mechanical gauge, if low (under 25psi) the car will idle, but pressure is not suffecient to run engine under load.

Also check the fuel pressure regulator vacuum line for presence of gas, which would indicate a ruptured diaphram.

The speedometer is a seperate issue, most likely a vehicle speed sensor.
