Question about Cars & Trucks
Crank sensor tests ok do get anti theft code but mechanic says hat is secondary
Check if the injectors are pulsing when cranking the engine over. Listen for the tick, or feel for the pulse with your fingertips, or buy a cheap "noid light"-an injector circuit tester- one that fits your injector harness connectors-plug it into an injector connector and crank the car. If circuit is working the noid light will be flashing.
Some anti-theft systems immobilize the injector circuit when they are activated. So you have spark, compression, and fuel to the engine, check the injector circuit.

Try the ignition switch,
For the Crank sensor there is a small metal disc that mounts behind the sensor if that is cracked or dammaged or installed backwards you will get same results as if it wasn't Make sure the timing marks line up on your timing belt. www.kiatechinfo.com

It sounds like the vehicle is in theft mode,did you use a different key? Does the theft light blink really fast with the key off?If the passive anti-theft system has been activated the computer will have to be reset in order to get the vehicle running again.

try to start the car, than the anti theift would shut the car off. you wait ten min with the key on, until you see the anti theift flash or disapear. than turn key to off position and try to start it. this will reprogram the computer.. Good luck.
you can also try disconnecting the battery for 30 minutes

The sensor is part of the ignition key lock cylinder, so the part and labor will be around $200-$300 depends on your local labor rate, the dealer must do this repair because the new lock cylinder key code must be programmed into the VATS module.

did you use aftermarket crank sensor? if so that might be your problem. dealer has several different ones, by providing vin number, but there is only one after market for all optimas 01-05. try to connect thick pink wire and thick orange wire together on the ignition failure sensor. you might have the same problem as me. good luck.
