There are many reasons that a vehicle will not start so it is unlikely that this is an ignition switch again.

When you turn the key I am going to assume that you get a click or the starter does not turn over.

If that is the case then we need to follow this guide:

Basically we need to go to the starter and check for voltage on both wires.

Please see the wiring diagram below for more detail on this but this may just be a simple starter solenoid that failed or even a clutch position switch.

So let me know what you find with this and we can go from there.

Thanks
