motor wont start, where shud I start?

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?

Thanks for your input. My car is a 4 speed so I dont have to worry about shifter linkage or neutral switch. But yes - I was wondering if I should check the starter relay or solenoid or something like that...
