95 Powerstrock 7.3 Replaced the starter relay, and the switch under the steering column. Power is good everywhere. When I turn the key, the glow plugs activate, as usual. When I turn the key to the start position Nothing. No click nothing. When I jump the starter relay the truck fires right up. Alternator fires and charges. However, the odometer doesn't activate and the ABS light stays on. Thought the actuator was bad so took the switch back off and ran it manually Still nothing.
Any thoughts?

Remove and charge both batteries, plus clean the battery terminals and cable connections. Most auto parts stores will charge batteries for free. If necessary, replace. My bet is that the batteries need replacing. This link may help:

Have done that already. When I jump the starter relay it fires right up.

Check the ignition switch for wear, pitting, or melting, disconnecting the negative battery cable first.

Ignition switch is new. Just repaced it yesterday.

Is all of the wiring good?

Far as I can tell. Fuses checked out good too. Should the signal wire attached to the starter relay show power to it?

Do you have fuel pump wiring under your dash? If so check for burnt wires or disconected taped etc.. this will cause it to start from a different sourse then your battery starter alternador ignition etc... ;) hope u figure it out good luck
