Will not start on key shift indicater light only comes on when key is between off and run no power to starter solenoid trigger(purple)wire,will start with key on and jump terminal at starter,will also start if I pull starter relay and jump across 85 and 86 pins and turn key to run once running must pull jumper wire off to release stater soliniod,nuetral safety switch yellow and purple both have power when key start or run maybe ignition switch not sure how to chase purple wire from ign. swiotch to starter solenoid thanks for any advise
From the ignition switch there is a yellow wire that is for the starter. probe it when trying to start. If you have no voltage replace the switch. Also, I believe there is a fusible link in the wire by the starter. It will be a different color than purple. Probe on the back side of it to see if there is voltage at start up. If so, replace with the smae color link.

The neutral safety switch is located in the shifter housing.
Here is a link to a good article on this topic, that would beat an explanation from me.

Yes, it sounds like the NSS is the culprit.
SOURCE: No-start condition, starter & ign switch ok
yes the park neutral sounds like where your problem is
you could use a test light to check .
SOURCE: engine wont crank
im looking at that circuit , on the start relay on your radiator support , red is always hot via fusible link , purple to solenoid as you say , orange/black wire should be hot in run or start mode , if it is not the fuse for that wire is PCM/ABS 10 amp located fuse block in driver door jam , it does go through the nuetral saftey switch , the yellow wire going to the PCM must ground that relay to activate start mode . last note there is a PCM/CRANK fuse in the driver door jam also , 10 amp , if all this is good i would like to hear more . 1 more note about the nuetral saftey switch is the pink wire going in and the orange/black wire coming out should have continuity in park and nuetral ....let us know thanks

Is your security light flashing ?if so you have a problem with the anti theft system.Leave the key on for 10 minutes ,then try this should reset the anti theft system
SOURCE: Purple solenoid wire shorted, no pwr coming from ign switch
look for a 5 amp fuse, crank fuse in car, not under hood
