What do I need for my vehicle my car will not crank when I turn my key to the on

I mean my car will turn over but it seems I have to play with the ignition switch in order for it to catch then it will act like it want to crank but cut right back off seems like I'm not get any gas up there for it to stay crunk...and like I said I can get in there and turn my key to the on position and no dash lights but I have experience this before that when they do come on my car will crank so now u tell me wat u think it is...I tried cleaning the battery post

if your theft light is not on,which i don't think it is,i believe you have an ignition switch problem.

So what is it somebody said alternator now I'm hearing ignition switch ...no lights not coming on at all when I turn my key to on position

you would be surprised at what the ignition switch is for.key switch is around $200.00..ignition switch is around $60.00..alternator is around $120.00..battery is around $120.00...

I tried jump starting it from another vehicle....lights still didn't come on dash and it turns over but want crank...this just happen all of a sudden...the last time I driven it it was acting up the same but the dash lights was coming on when I put key in switch...I was riding and all of sudden my Air conditioning stop working because my compressor was not turning so then about a hour with my car just sitting at my house running all of sudden compressor kick back in so I think it's some kind of mechanical problem...my temperature and gas hand stuck but when the lights come on dash the hand drops back to were it suppose to be so what u think

you will need some hands on help with this.

All I need to no is wat part do I need to get to solve this problem I just don't want to spend money on parts I don't need so will u please tell me what u think the problem really is

instead of you throwing parts and money at it,i would get some hands on help with it! and start testing everything,otherwise you would just be guessing at it..

stevieray1 is absolutely right! Testing and diagnostics are necessary so you don't waste time and money throwing parts at it!

So if u had to guess wat would u say it is

So u don't think it's the ignition switch or ignition coil

we don't know...we all here are trying to help..read Unclephil71's reply! it's well worth checking out.
