Car was driving down the road and died

If the fuse blows and a smell of burning is present then its obvious there i a fault somewhere ahead of the fuse, the fuse is a protection device.

A repair shop--- to diagnose & actually
find problems ,not throw parts at it, with
no testing

You have a an electrical short on the starting circuit.

u have a dead short on main live wire check for overheated wires

That fuse powers the pink wire that runs to the coil, injectors, and pcm.
If the short isn't obvious, I disconnect everything I can from the wire and then put in a fresh fuse. I turn the key on and check the fuse. If it blows, I know it's something I haven't disconnected or the wire itself. If it doesn't blow, I start reconnecting things one at a time untl the fuse blows again.

you may need a new computer module. you can check for shorts by identifying where the computer module is and following the wires to your fuse box. this may take some time to do. also check your fuse box and make sure it is in good condition and has a cover, no rust, etc. best bet is to get a chilton's repair manual for your vehicle at a local autoparts store. about 28 bucks. especially if you need to do this on your own. this will help give you the correct procedures for identifying and fixing things.

I don't want to seem like a smart ****, but the blown fuses were telling you that something with the component that it was protecting is going bad. So changing the fuse the first time was a go idea, the second time was not. It told you, that something was failing and you refused to pay attention.

But at least you know which fuse blew, so now all you have to do is find out what it was protecting and replace it or what feeds it.

Many cars have the cooling fan on a thermostat or time delay, to allow it to run for a short period of time after the engine turns off, to cool the engine off. You may have just never noticed it before. So I wouldn't worry about that.
Your real problem is the blowing fuses, apparently you have a short somewhere in your wiring. Putting in bigger and bigger fuses is a great way to set fire to your wiring harness. It's possible that the wire is pinched or chafed somewhere, and perhaps when you hit a bump just right, it touches and shorts.
You may have to take this to the Chevy dealer or a GOOD independent shop to have them chase it down. Unless someone out there knows exactly what this is, it could be a tough one to find.

Its not the packs, I am pretty sure that is the distributor in the engine, (the one the coil pack hooks up to) I thought I knew my stuff until a 15 year old neighbor kid came and fixed my sundance that way, that or its a loose battery wire. hope this helps, have a nice day, and drive that thing like it was meant to be driven!

I would say that you are on the right track , I think that maybe when the work was done on the fuel pump assy the mechanic may have pinched the power wire and hitting the bumps has caused it to short.you will have to take the seats out again (sorry).You need to look for a damaged wire or evidence of arcing .Hope this helps.
