|If quits while running. Starts sometimes, not others. Turns over but won't start then likley the ignition switch, not the key barrel, but the switch itself. |
This sounds like a classic ignition switch problem. Make sure it is replaced and not the ignition lock cylinder!
The ignition module below the ignition key will fix the truck. A loose or worn connection in the tumbler box would sometimes cut off the power to items in the truck, the brain, the fuel pump... ect.
Ignition module is a little black box and wires below the ignition key, it is approx $100 to replace and truck runs ... no stalling or no start conditions anymore.
To replace the ignition switch
• Torx bits (get a set, you need 3 sizes) Inverted Torx ( a set is available at Schucks/Kragen/Checker
• A few zip ties
• Wire cutters
Remove the skirting under the dash area and steering wheel.
Disconnecting the yellow wire under the dash on drivers side for the airbag.
Leave the airbag alone if possible, it may not be necessary to remove the steering wheel.
Now remove the lower column cover with 2 Torx screws.
You will now have access to 2 inverted Torx screws that hold the top column cover in place.
Look on the top of the ignition cylinder housing and find the small hole.
Insert a small Allen wrench into the hole and turn the key to "run" position and the ignition cylinder will come out, now the top cover will come off, giving access to the ignition switch.
You will need the smallest inverted Torx bit for the 2 screws that hold the ignition switch in.
You will have to cut a couple of zip ties to free the wiring.
Now get a Torx bit and a 7mm socket and remove the lower dash panels to get access to the wiring harness.
You will need the 7mm to unscrew a bolt that holds the connector together under the dash. Just follow the wiring to see what I mean.
Once the connector near firewall above foot area is loose, you will see two plastic strips that run along side the connector. These are easy to remove and slide off, and are keyed so you cannot reinstall them wrong. Hope this helps.
