Default 3800 Series 1 in Olds Trofeo. Ignition problem

So to begin the explaination part, the car decided it was going to go ahead and blow the
Ignition module fuse suddenly\, it had done this before, needed to replace the coil packs, and I did. so I replaced the fuse, and it did it again, so I went to the parts store to get some more fuses, heres where it gets cool. so I get a pack of 20 amp fuses, put one in, start car, it dies. hmmm... so I check, its blown. so just to see, I put another in, turn to on, boom, again, blow, again, blow. I went through the entire pack. so I have to get home (which is only 5 blocks) so I opt to get some 30 amps and see if one of those will live loong enough to bring me home. I get them, put one in, boom, put another, boom, another, boom, Ive got one left, so I put it in.... it runs? hmm... so I get home and next day Im driving to work and the car dies, this time no blown fuse. car only cranks, no start.

now, Im getting no spark (I took a plug out and watched as I cranked it, it didnt spark at all) so I got a coil pack, tried it, nothing, so I exchanged for the control module, nothing. So I kept the control module and plan on getting the coil pack and seeing if both of them blew. Is this feasable? what could have happened? if new coil pack + new control module = still no what next?

Thank you so much for any help?

Default crank sensor

first of all you're an IDIOT for putting more than 1 fuse in anything that blows the fuse. there is an obvious problem that will not fix itself, under normal operation a fuse will NEVER blow!!!! i suppose i could let a second fuse slip, but what the heck is wrong with you putting what...ELEVENTEEN fuses through there!!!!! now that i have that off my chest, replace your crank sensor. you have to take the vibration damper off the crankshaft, which depending on the car, is very easy, or a huge pain. some of them slip right off once you get that GINORMOUS bolt out, and most of them do not come off without a puller...which it was not designed for. i had to modify a 3 jaw puller to work with it... but if you're blowing fuses, i say you have a short somewhere. what about when you put the coils on the module?? are you pinching the wires in there? ( i assume you have the magnavox 3-in-1 coil pack)
