Drove to gas station, filled up, and wouldn't start. Lights come on. No attempt to start.


Jumped truck with our van and truck made no attempt to start


Took starter to advanced auto and they told me the starter tested bad. I did see it test bad. Bought a new 1 and put it on. No sound when key is at crank.


Jumped the cylinoid with they key in the "on" position and the truck cranked but didn't start. Seemed to not be getting fuel.


Found my other key incase the chip went bad, and didn't start with either key. Won't attempt to start.


Had someone turn the key to crank and tested signal wire on starter and got no current.


Checked fused under the hood and all were good. Swapped starter relay with other and made no change.


Replaced ignition switch and made no difference


Next step?

1. Let's assume "No attempt to start" means that the engine did not crank/spin. THIS would've been the time to troubleshoot whether the starter solenoid terminal was getting 12 volts positive when the key was in the "Start" position. Now you've just muddied up the water by installing a starter and ignition switch.

2. Does "Replaced ignition switch" mean that you replaced the tumbler/key part or the electrical part?

3. To get real help, you need to post details in more clarity.
