Hey Nismo, i gotchu on this... alright well im new to this altima.net thing so yea this mah first post trying help you out... ayte its like this well if you want your car to the autoshop its either wat everyone else sed, tap the stater or if your car is manual you can had someone push while its on first gear and quickly pop the clutch and it should start.... ayte well if you really need to change the starter its about $150 -$200 so yea if you really want a new one you could go that way or if not.. go look for a junked up altima or used parts i just recently change mines about a week ago i got mah starter for $60 and i put it in mahself.... ayte you cant see the starter when you pop the hood it right under the engine. between the engine and firewall... its under there some where it should look like this
if you locate it and tap it and doesnt work and you can get someone to fix it for you or fix it yourself. it took me about less then an hour to do it... but yea its a pain in to get it out... alrite well to replace it theres 2 long bolts holding it in place and one that connects to the battery. before you start at it be sure to take the neg wire off the battery so you dunt kill yourself. well to get started you either need a lift or the hard way get a jack and just jack it up and go under. you should first disconnect the electrical wires. then start taking the bolts off. you can do this from the top of your car to make room you can take your intake box off or watever kind of intake you have. this will give you more space. you need a long sockect wrench to take the two bolts off. after doing this you replace it with the new one you change have someone help you hold it in place while you screw the bolths back on or you can get something to wedge it there for you. ( i used some rags to hold it in place) then connect the electrical back on and the battery and you should be good to go.
Mah car is different from yalls but it should still be the same i had an SR18 engine and swap a SR20 starter to it. i have a nissan bluebird not an altima but its almost exactly the same so it should work.
alrite well good luck on this yo.
