anytime a gm wont start you need to get the hammer out and give the solenoid a good whack or 2 ,if your sure battery is good If you turn key and it all lights up but as you twist to crank mode nothing happens then its likely stuck solenoid and just in case you got a bad pedal switch( new ones are junk anymore) you can simply bypass it with a wire just make the connection between the 2 plug ins and make sure its right switch also .some have 2 switches and one is for cruise control other is clutch /start but anyway smack that starter or have someone push in clutch and hold key in crank mode while you beat that starter with a hammer best o luck
