Does anyone have a pic or diagram handy where I can find this sensor? Thanks!

 

its in the ignition lock cylinder itself.

 

When you replace the sensor does it just disconnect from the lock cylinder?

 

sorry it took so long...but I made a mistake, the passlock sensor itself is in the ign lock cylinder case and is not serviceable by itself as far as I know. You have to replace the complete lock cylinder case. heres a pic to better understand. What kind of problem are you having to justify replacing the passlock sensor??

 

The truck has 60 psi fuel pressure, plenty of compression, good battery but no spark and the security light has suddenly appeared on....

 

Replace the lock cylinder reprogram the passlock and you should be good.
