Diagram to replace igntion wiring

Sounds like you have a bad igntion switch or other electrical gremlin somewhere. If this is something you bought like this, then I would get a service manual with a wiring diagram and ensure the wires on the key switch are in the right positions.

Can replace ignition switch w/used unit for around $100

Not sure but call the dealer they should be able to cut you a key from the VIN number.

There is a break in the wire that supplies power to the fuse box.
You need to trace this power wire from the fuse box to find the break in this wire and fix this wire,.
Ii would help you is you have a wiring diagram of your vehicle as the wires are color coded.

Hi. You can get the wiring diagrams from this site.

first things first check your fuses and i mean all of them replace all that are bad with proper fuse amprages

you are going to have to do some probing of those wires to find the ones you need you can buy a voltmeter(25$ or less) or a simple test light(2-5$) from a local automotive store

colors to look for are
primary power wires :red,yellow, black for ground
accsesory wire from igntion ,orange or blue with wite stripe and posibly pink(rare)

any wire that has an on and off state from the turn key igntion can be used depending on its gauge/size test the orange one first as this is the most common color to use for the accsesories wire
to test you have the igntion in the on postion if you get a readying of +12 volt and then turn the igntion of and recive a reading of 0 volts this would be an on off wire
note: check the auxsilary postion of the turn key igntion also if there is no power to the wire in the auxzilary postion it is the incorect wire for the radio

BLACK> should be a ground wire
RED>should be an igntion supply wire of a larger diameter
YELLOW> should be a battery supply lead strait from the fuse box battery conection "always on"connect the wire of the stereo labeld battery to the always on battery lead ,this is for the memory function of the radio

ORANGE>(may be pink only seen pink in buick's) should be an on/off wire from the igntion and used for the main power of the radio so it is shut of when the car is turnt of this is also the wire you would hook the amplifyer on off up to if the radio dont supply the blue wire with white stripe aka ant/motor
test the on off state of the wire befor conecting it to the radio
you will conect the red (+ positive) wire to this on/off state wire

cation! disconect the batery ground wire when conecting anything to the main yellow battery wire as it is directly conected thru an exspensive(12$) 30 amp fuse

if you dont know what wires are what for the speakers in the car use a 9 volt batery to find the speaker wire leads (ues a brand new 9 volt)
ntsc standard color pairs are
white and grey front
green & brown for back
i dont remeber the left and right
the black stripe on the speaker leads means the ground or negative side of the speaker
good luck instaling your new radio hope i have helped you out

most likely the tiny wire from the igntion cylinder to the security module is broken. First try using another key, if the other key didn't fix it you'll most likely need to replace the igntion cylinder.

can't be reset. the security system consist of the igntion key, igntion key cylinder, wire harness and module.
the most likey cause of this is the tiny wire harness from the igntion cylinder to the module is broken where it goes into the cylinder.
you can try using another igntion key, if still persist you'll need to get this fixed, sooner or later this will not allow you to start the engine.

It's possible the "anti-thielf" system has been failing and went out while you was driving. If the ignition key has a chip in the shaft of the key your car has anti-thieft. It's possible the system doesn't reconisethe igntion key and shut the system down. Try using another igntion key if it came with 2 keys. If the engine started you'll need to get the other igntion key replace.

I have the same problem. My key is stuck and won't come out
