i dunno wuts wrong i installed it jus like it was and now my starter just makes a noise like if its going to start but my engine aint starting i insert the cables correctly please help !

 

Do you mean the engine turns over but does not catch? or that the starter doesn't crank the way it should? If it doesn't sound like it is cranking fast enough, the new started might be trash. Just because it's new doesn't mean it can't be defective! It happened to me, had to re-install the old starter and go buy a new one from Nissan. If the engine is cranking ok and not firing, you may have knocked off a sensor wire, check all the wires to make sure nothing is lose. Hope that helps, albeit late.

 

yes check all your connections, check the mass air flow sensor too. check the vacume line
