i changed the battery and alternator, now heres the problem im having, not all the time but it does happen from time to time, when i go to try and start the car it doesnt turn, nothing, thats why i thought it was the battery, plus the battery was old so it needed changing anyways, so im thinking its either the starter or the ign, how would i know which one is causeing the problem, when it turns over the starter sounds fine, doesnt wine or anything but im not sure if somethin is loose or the ign is starting to go, any help would be great because im afraid of getting stuck somewhere and not be able to get it started. BTW its on my 88GT with 161k on her
