1993 Ford Tempo

Electrical problem
1993 Ford Tempo 4 cyl Front Wheel Drive Automatic 100000 miles

When I try to start my 1993 Ford Tempo, as long as I hold the switch to start it will start and rev up but as soon as I let go of the key it will die. Is it the ignition switch and if so how do you change it.
Thanks for your help

It is your ignition switch

Disconnect battery ground cable, then remove five steering column shroud attaching screws.
Disconnect battery ground cable, then remove five steering column shroud attaching screws.
Remove two bolts and two nuts attaching steering column to column bracket, then lower steering column assembly to seat and remove column shrouds.
Disconnect ignition switch wire connector, then rotate ignition switch lock cylinder to the RUN position.
Remove the two retaining screws connecting the switch to the lock cylinder housing.
Detach ignition switch from actuator pin, then remove switch.

Check to ensure that ignition switch actuator pin slot and ignition switch lock cylinder are in the RUN position.

Ignition Switch

Install and tighten screws to 50-70 in lb.
Connect wire connector to ignition switch, then connect battery ground cable and check ignition switch for proper operation.
Position upper shroud on column, then raise steering column and install column mounting bracket to instrument panel attaching bolts. Torque bolts to 15-25 ft lb.
