Ok so I have a 99 f250 superduty 7.3 that suddenly will not crank by the key if I jump the solenoid with a wrench it fires right up but the key will not even try I replaced starter solenoid and ignition switch still nothing I have tryed putting in every gear and it still won’t start when I turn the key the relay under the dash clicks and that’s it the trigger wire on the solenoid is getting 11ish volts when you turn key but nothing happens you turn the key and the radio turns off but none of the lights dim or anything I am a loss

Welcome to the forums! Is this a manual or an automatic? There is a safety switch mounted on the clutch master push rod if it is a manual. On the automatic I believe the safety is part of the shift selector that mounts to the side of the transmission.
