My '89 GT will fire right up when it's cold but after it warms up it's got a hard start. It's been doing this for a few days now when i stop at the mini mart or to get gas on the way to work. When it's warm it will turn over fine for a split second then turn over very slow and fire up.

I tested the battery and it tested fine , i was going to voltage drop the starter. The ground look good from what I can see. any chance it could be an ignition switch? Because I have one sitting in my glove box i could throw in.

I like the voltage drop testing idea.

Do you have LT's?
