ok, my 90 gt starts when she wants. I replaced the battery yesterday and she started right up which is nice. well i drove her for a bit, and when i brought her back home, about 10 minutes later my dad takes her out for a spin. he gets gas, an she wont start back up. he kick starts with a push. he gets her home safe and sound, an hour later, i try to start her and no start, just a half ass turn over but no fire. this morning i go out to see what would happen, she started right up. i drove for about an hour and comesome, shut it off, then try to start up right away and again, just a half ass turnover and no fire. I went out a few hours later, it started right up, i shut it down, started up again, and no start. Then after about five minutes, she started up 5 consecutive times in a row, each getting weaker and weaker each time. This problem has been going on for a few weeks now, and i am aware of the fox body nightmare ignition. but im clueless as to what this is since im a total noob. any help would be excellent before i start replacing shit.

it seems as if it takes alot to start as well, sort of like the starter doesnot get enoght power, turned over very slow.

check all of the grounds, add a couple more.

I used to have the same problem with my 5.0 Grand Marques.
Found out when the starter got a little hot it was really weak. Once it cooled down it was fine. I used to get stuck with it at times. A couple of times if I gave it a Jump start with Cables it would start. Other times I would have to wait till it cooled enough to start.

I was also thinking it sounds like a atarter problem. You may need to pull it off and have it rebuilt or buy a new one.

Its definitely the starter. If you get a new one, get one from a 93-95 Mustang or 96-99 5.0 Exploder. They come factory with a high torque starter. If your headers are getting your starter too hot, this would be a good time to wrap it with header wrap to keep it cool.
