Someone broke into my truck last night and broke my ignition switch. Truck
turned on but once I turned it off it wouldn’t start again. I changed the ignition switch that was mangled from them trying to steal my truck.
New ignition switch and still no start. I can’t figure out where the no start is coming from.

This is how I found my truck after the break in.

 

You say no-start, but do you mean that it won't even crank? No dash lights/response?

If so - have you checked the fuse to the ignition switch?
