My car keeps blowing the start/fuel fuse. I keep replacing them but do you know what is causing them to blow all the time?

Which fuse is blowing? Could be something wrong with wiring circuit or fuel pump?

Like I said something wrong with wiring or fuel pump. Does the fuse blow as soon as you plug it in?
Your talking about the #8 FUSE--20 AMP IN THE DIAGRAM, CORRECT?

Yes, that is the fuse. No, I put in a new fuse and the car will crank. When it blows it wont crank. It will work or a day or two or even a week then one day I'll go to crank it my car won't crank and that fuse will be blown.

I looked at your power distribution wiring for that fuse. It also sends voltage to starter relay and ignition switch, besides fuel pump relay. I'd have to separate those circuits and check the amp draw on each circuit. See if anything looks suspicious. Intermittent issues can be hard to track.
