Question about 2003 Ford Focus
Sounds like your vehicle security system is at fualt. there is a transponder in the ignition that reads the key while in the ignition and if there is an issue with the resistance it will not let it start.
you can check the starter wire at the ignition switch. it is a gray with black wire and if you have power there check cavity # 85 of relay socket while turning key if power is there then check # 30 to see if there is constant power there if not check fuse f1.8 30amp .
that fuse gives the relay constant power to power the solenoid. the gray with black goes to the #85 of relay but has no direct connection to the solenoid. do you understand how a relay works?

Did any one bother to ask how many miles were on this vehicle??? Was the ignition switch actually tested for power out??? I don't want to get involved at this point, but my previous question is a valid one to say the least....................

If you test the supply wire which comes from the ignition switch to the starter relay. Disconnect this wire out from starter relay in back of the fuse box and with a multimeter check the voltage between this wire and chassis earth ignition key in "START ENGINE" position! If you find +12 Volts then ignition switch is in good condition. If not, then ignition switch is out of order!
