I just replaced the battery and the alternator. I went to start the truck and it will not start! If I hold the ignition forward with the key in it it will start I let it off just a bit with minimal pressure holding it forward a tad it will stay running, but if I release the ingnition swith it dies. Why is this.

Hi joshuaepling,

Thank you for the donation.

The ignition switch is faulty and has to be replaced to rectify.

Do you mean the tumbler/cylendar that the key inserts into or the actual electrical component called the ignition switch. I've heard them both called the ignition switch and want to make sure I replace the correct one as this truck is stuck on a military base with limited access. Thank you

It is the electrical part connected at rear of steering lock.

The tumbler is known as the key cylinder or lock assy.

Yes, it is under the steering column but I am not able to get any diagrams to show.

Removal ("E" & "F" Series)
Disconnect battery ground. Remove steering column shroud and lower column.
Disconnect switch wiring at multiple plug.
Remove nuts securing switch to steering column.
Lift switch vertically to disengage actuator.
Remove switch.

Installation ("E" & "F" Series)
1. With lock cylinder and switch in LOCK position, engage actuator rod in switch. New ignition switches come positioned in LOCK position with shipping pin in side of switch. Position switch on column and install retaining nuts, but do not tighten.

2. Move switch up and down along column to locate mid-position of rod lash, and tighten retaining nuts to 40-65 INCH lbs. (4.5-7.3 N.M). Remove lock pin and connect battery cable. Check for proper starter operation in Park and Neutral. Raise steering column into position. Verify accessories are not on with ignition switch in OFF position and are on with switch in RUN position.
