For the last year every blue moon i would try to start my car and the key would not turn i would jiggle it and force it to turn it finally would not move at all so i bought a new ignition switch now it turns but will not start at all is there a kill switch or some sort of security problem i searched threw the fourms and couldnt find any thing any help would be Gratefuly Appreciated

 

I forgot to mention i change main relay i made sure i could hear my fuel pump it has gas in it i checked all fuses i even change egr valve and cleaned out manifold and egr port

 

Any suggestions

 

did you replace the key part?? or it AND the back part where the electrical is located?

99s had a severe problem with that electrical parts failure- it carried in to later years as well

does the green color KEY flash on the dash when you go to start it?
That's the immobilizer verifying status

 

I replaced the whole ignition actual key entry piece and just the white ignition swich part thats connected by a wire harness that clips in under dash. While im trying to start the green key is blinking

 

Since you replaced the key lock cylinder that means you are now using a different key to try to start the car. This is why the car will not start. There is an immobilizer system installed on these cars to prevent theft so not any random key can be used to start the car. First make sure the new key has the provided chip inside, then find the diy on how to link the key to the immobilizer system. If you dont want to do it yourself, you can get the dealer to do it for you.

 

Ok im using the key that came with the used cylinder i bought and i cant find a diy for linking it to the immobilizer imma try taking it back and getting another thanks for the response maybe the junkyard gave me a broken or no good switch and key and cylinder i wounder do the diffrent years mean anything i have a 99 but the paper work say its a 01 they gave me

 

Its not the key or the switch. Since you replaced the whole thing key included you HAVE to bring it to the dealer or a locksmith capable of reprogramming the immobilizer system to match the new key.

 

take the word of our Guru of all things TL= fsttyms1 (Fast Times Won!)

get out the phone book and call a locksmith, they come to you rather than tow car to dealer
An independent shop/owner is usually better than big ad/ big name type place

 

Damn yall was a big help i called a locksmith (one who specialize in immobilizers not everyone does it) he reprogramed the key to the immobilizer and now it starts thanks for the help

 

Oh, and while your at it you should change the tumbler pins in the door locks to match your new key incase your fob ever stops working, tyhat way you can still unlock the door with your new key. There are youtube videos on how to do it

 

Good thought imma look into that
