'75 Delta won't start with turn of key

heres the situation.

my Olds runs, starts and everything. i just have to crawl under it and cross the posts on the starter with a screwdriver.

the problem is that when the key is turned, it wont even make so much as a sound.

so i cross the starter posts, use the key to unlock the column and then i can drive it anywhere i please.

i dont want to turn it into a demolition derby car quite yet and would prefer to drive it a bit longer, despite rising gas prices.

any help would be appreciated.

thanks.

Try replacing the ignition solenoid.
