Is it still doing the same thing(starts and as soon as you release key it stalls), if so bypass the resistor and see if it ll run (only do this for testing purposes , do not drive like this) , if it runs then it is possible the new resistor is faulty as well (new does not allways equate to good)!Could be the ignition sw. but before you start tearing into the column or anything else for that matter you need to test a few things (min tool would be a test light but better with a multimeter some small ones @ hardware stores somtimes as little as 10bucks)see if you have power at resistor with key on , go to
