Replaced Stereo, Now Car Wont Start

hi, my name is david, and i need a little advice from you guys,

1994 honda civic dx : i replaced the original factory tape deck with an alpine cd deck, the deck works fine, and all dash lights and everything come on, no problem it seems, but now the car wont start. it will crank as if trying to start, but engine wont turn over. i dont understand. i cut the harness from the wires coming out of dash, and rewired the alpine harness to them, everything done neat and clean, but while wiring the alpine harness a power wire from dash touched metal and sparked, blew 15amp fuse, and i replaced the fuse, no problem right? everything still powers. the car is also equipped with a micro-lock security device, that makes me have to turn the ignition to on and wait for two beeps to start, and it still beeps and twerps like it should. the car would crank but not turn on one attempt, and the next attempt it would "click" and stop. i tryed taking negative cable off battery for about 2 minutes, even tryed new battery. i checked the fuses under dash and hood, all good. honda dealer said over the phone that the factory deck must be left in or it wont start, recomended that tuck the honda under the dash?, but that dosnt make sense. he said that a car audio store will sell a "bypass harness", but audio express never heard of such a thing.

so that is my situation, hope i didnt make this subject to long, i really appreciate any advice or suggestions on this, cause i am clueless and broke as a joke so not many options here. thanks for your time

hey thanks guys appreciate the suggestions, because i still havnt been able to solve this problem my self.

yes it has a yellow/red wire that is the 12v+ switched lead. also, a blue/white wire that is what i assume is the 12v+ constant power, wich the diagram of the harness on the asctual tape deck refers to as "battery, (back-up)" and another diagram i found as "memory". so i will try rewiring the honda harness and wiring the alpine harness right to the honda one this time.

and i will definitly test the voltage from that ignition switch wire.

you guys are genius's. i will contact your employers and demand they give you raises.!  

oh yes and i am in Phoenix, Arizona: born n raised n stuck ba-by, thanks for the help fellas

"the car would crank but not turn on one attempt, and the next attempt it would "click" and stop" ...when it was cranking, did it sound like it was slow at cranking?  and the secone time you said it would click? sounds to me like the battery is power is low, if you haven't already, try getting a boost from a buddy or charge your battery over night, and try it agian

yes the dome light i had on the whole time, and i did try a whole new battery that was pretty much brand new. i did find the micro lock security device under my dash. it spliced from the ignition wire and the starter wire and the battery wire at the ignition harness and ran into a relay or something that beeps and makes you hold the key in the on position before starting for bout 3 seconds and then lets you start. i took that out of the circuit. still wont start. however the starter is cranking but it wont turn over. i did hook the honda stereo back up to, and it works. all fuses are good, all accessorys work, and then i found a gps device taped up and hidden deep up in the dash that has two wires coming from somwere on top of the ignition. i pulled the device out but havnt traced down the wires or anyhting yet, still wont start. i assume the gps was from the dealer incase to repo. still dealers wont give me info. all i have left to try is to borrow a volt meter hopefully tonight and check voltage's everywere.

i appreciate everyones help. this really sucks and i am really having a hard time getting it figured out.

respect.

i had one of these a while back that haunted me.... it would crank and crank but not start after i put a remote starter in it... after trouble shooting all my wiring for about 2 hours i traced the problem to one leg of the ignition switch not powering up an ignition wire....  it turned out that if you used the tilt level and moved the steering wheel at all then the car wouldnt start, but if you found the sweet spot and left it there, then the car started fine.....

it could be something wierd like this.... or a wire you have accidently cut.... do what i did and as Jeff suggested and meter every ignition wire coming from the switch..... also, check every fuse in every fuse panel on the vehicle (especially the maxi's)... there are often more than one fuse box so be diligent....
