Computer problem

I have a problem of the car not starting yet it is cranking. Even the fuel pump relay does not go on. When I bypass the fuel pump relay the car starts but does not respond when I push the gas pedal. What shall I do to solve that problem.

You may want to consider the crankshaft position sensor being faulty. This will often times cause a crank no start condition. Also if my memory serves me correctly this is one of the inputs for the fuel management system so this may cause the pump circuit to not power up.
