bad starter maybe?

[robcarync]

well...in the last few months...on my car...ive had a guibo replaced, an o2 sensor replaced, brakes replaced, inspection II service done, rear differential seal replaced, radiator hoses replaced, and a few other repairs done that i cant remember.

now my car is having trouble starting. i think its the starter (so does my dad and mom). but basically i turn the key, and it rolls over, but the engine doesnt get turned on. its a bad description i know, but its like trying to crank a car with a dead battery.

any way...assuming it is the starter...how hard is this going to be to replace, or should i take it to a mechanic (forget the dealership...im done with those goons). im only a beginner mechanic...but my dad has replaced the starter on previous cars (jap cars though)...so he has some auto experience. would this be terribly difficult to do it ourselves?

so i guess...anyone know where i can find a write up on how to change a starter?

anyone else have any ideas as to what else could cause this problem? i dont want to invest in a starter, and still have a problem cranking it. is there a sure fire way to tell if it is, in fact, the starter thats causing the problem?
