check the solenoid on the starter it powers the ign for starting then switches to run when you let off key,either the solenoid is bad or a wire to the solenoid has come unhooked and sometime they have an in line fuse which can blow.

SOURCE: no power at fuel pump

check the emergency cutoff switch for the fuel it may be bad or have tripped it is usually in the rear compartment of the vehicle
