drove to the store perfectly fine and went to leave and the car wont start i checked the fuses i found that the 30 amp fuse to the engine was blown(at least thats what thee fuse box cover labels it as) i changed the fuse with another 30 and it blew when the car was turned over the next time. i have looked for burnt wires and shorts i do not see one that is blatent but am wondering if a compnent burned up and has an internal short.

 

I had this problem with the 20 amp fuse in my 2001. On some rainy days, it would take five fuse changes to get it to actually start without blowing. It happened quite often until I had my fluids changed. Transmission fluid is my guess for what was the solution (dirty and thick fluid caused the starter to need too much power to start).

Problem could also be a short in the starter motor itself.

If the problem is intermittent, you could try using a higher-amp fuse. But, I do not suggest that and will not admit that it worked on my vehicle.

Probably not the starter motor. The starter motor draws a couple hundred amps or more. The starter current doesn't go through any fuse. The starter relay draws a little current but permits a big current to pass.
You didn't say whether this was a convertible or a coupe. (They are quite different.) I'm guessing coupe. I believe the fuel pump may go through that fuse. The auto shut down relay may also go through that fuse.
Check for codes. If there's a fault code you'll save a lot of guesswork.

 

It's not the starter motor... I've had the same problem with my 96. First it was a fuse, then the convertable top wouldn't go up, then it was a relay. After hours of following wires I decided to pull the boots all the way off the terminals....What a mess. You have corosion somewhere. Most likey under your terminal boots.
