Ignition switches on our trucks go bad all the time, mine luckily only once so far. It is cheap enough that I would buy one and switch it out and if it isn't that just keep it on hand just in case for the future.

yes

I jumped the relay to test the starter... like took out the relay and took one piece of wire from where one prong would go to one of the others, which will start the truck.. well should , which it cranked over which should have bypassed the ignition switch and start the truck. it did crank over but no fire?

Thats why im confused if it really is the switch. Normally it should still start when bypassing it, i would think. which made me think it may not be the switch...

but i will change it anyway.. just a few bucks....
