motor wont start, where shud I start?

Yes the ignition switch concerns me... ever since it stopped turning over the engine several years ago and then I bypassed it. But I still need to turn the key to the on position before hitting my bypass rocker switch to start the engine.

But it seemed like a really difficult intricate job to swap out the ignition switch (hence the reason I just bypassed it when it failed originally). Is there a way I can bypass it totally... eliminating the need for a key to start it?

if you had to install a seperate start button thingy, try unplugging the NSS at the firewall and put jumper wire across it. chances are good the NSS is bad, the starter relay is bad, or the shifter linkage needs adjusting. have you tried putting it in neutral and starting it with the key?
