I have a 1996 F350 with a 460 engine and a C6 trans.When I turn the key there is NO noise,won't crank.It will crank and start if I jump the two big terminals at the fender mounted solenoid.I have a used solenoid that I tried with the same result.I checked the battery voltage and I have 12.5 volts at the battery.When I disconnect the plug to the "S" terminal of the solenoid and hookup my fluke meter I get 1.1 to 1.5 volts when the key is turned to the crank position.I replaced the ignition lock because it was sloppy and the outside thumb tumbler would turn without the key.The starter was checked before installation.I did find two wires in the harness near the transmission crossmember leading to the transmission mounted neutral switch that had the insulation chaffed off.I repaired those,still no crank. The original owner added a momentary switch under the dash to the starter solenoid so I would say theres been a problem right along. Any suggestions??

 

Try holding the gear selector in park and turn it over. Put some pressure on it.

 

Or neutral. This tells us if it's a simple NSS adjustment.

 

I forgot to add that.I tried holding the shift selector up and even moved it around slightly when holding the key to the crank position,no noise.I even tried cranking it in neutral.

 

The Ignition switch may need adjustment or replaced.
Try unplugging the Ignition switch and jumping a yellow wire to the red wire with a blue stripe and see if it cranks.

 

Are you referring to the switch at the transmission

 

No, the switch on top the column near the floor under the dash.

 

Not seeing that would a bad multi function lever switch cause a no crank? I have no power to the wiper motor or fuse

 

This might help you out:

 

I think I see what you are talking about.There is a harness that exits below the ignition switch (key lock) and travels down the column to somewhere at the base of the column.Problem is the weather took a dump around here and I haven't looked at it again.Anyhow if it cranks jumping the yellow wire to the red,blue tracer than what??

 

When I remove the small "S" terminal at the fender solenoid should there be battery voltage there when I turn the key to crank?

 

Yes there should be.

 

The key lock is not an Ignition Switch.

The Ignition switch:
