i was replacing all of the vacuum lines in my fc and when i finished the car will not turn on. checked the main fuse and it was blown... replaced it and as soon i hook up the batter it blows it out... I've gone threw about 4 fuses and still cant find out whats going on any ideas???

well you've obviously got a short from the positive terminal on the battery to ground, most likely the chassis. I'd check your alternator first and make absolutely sure the wires on it are hooked up right. I'm sure you disconnected the positive terminal on it when you redid those vacuum lines. If your key isn't in the ignition when you hook up the battery it can't be sensor wires since those aren't powered yet. The only other thing that could cause this that I know of is the starter but you shouldn't have touched that after doing what you said.

If those two things are fine I'd highly recommend getting a dmm(digital multimeter) and setting it to short detect mode (usually a picture of a speaker), hook one end to the battery ground and then touching various sensor wires. If there's a short it'll beep and if that wire you touched wasn't supposed to be a ground wire there's definetely something wrong in that circuit. You should grab the wiring section of the FSM to check which wires do what.

Make sure you didn't pinch any wires when mating the intake parts together. Also check for this where the upper intake is supported by brackets. Make sure you didn't take the ground wire ring terminal and put that on the back of the alternator, and do the opposite with the alternator battery wire.

i have now officially decided that i will never try to replace my own vacuum hoses

Do what was recommended above. Go to the alternator and pull it's large output wire off where it touches nothing. Then install a new Main fuse. Did the problem go away? OF a blown fuse, being the problem.

That same wire on the alt runs to the engine bay fuse box and also directly to the ignition switch (to feed the ignition pwr). IN the engine bay that same wire has a connection just below the engine bay fuse box. A single, black connector. See if that connector is fried or touching bare metal.

Yeah check to make sure the ALT wire isn't pinched or shorted
