Ignition will click once but not start the car. on 2001 Acura RL

If I pull back slightly on the key(exact amount of tension)the car starts right up....any ideas?

Asked by for the 2001 Acura RL
Due to the specific condition described about the key position , I would be really surprised if it actually is the starter. PLEASE post the actual repair , when it's done. I'm personally leaning towards the ignition switch, but that doesn't mean much(other than that I have poor balance).
My mech. put in the starter and since I got the car back I've started it up about 6 times with no problems.He must have been right,but I still don't understand it. Glad it was the starter,much cheaper than an ign. switch.
Thanks again for the reply and happy new year.

Bad ignition switch
That's what I thought.Acura says it's a bad starter.'It's @ another shop now,this mech. also says a bad starter.
New starter being put in now.I'll let u know how it works out.BTW 2nd shop charged 1/4 of the Acura estimate.
Thanks alot.
maybe your battery is low
Battery metered out at 12.71,thanks for the reply
