Bringing up an old thread here, not sure if anyones still watching this. But my security light came on. A friend of mine turned the key to the on position and pumped the gas pedal about 5 times then it started right up.

 

I tried this procedure and it worked the first time but when i take out the key and try to start it again it does the same thing. am i supposed to do it 4 or 5 times anyway or is something else wrong?

 

I have a question, during the relearn process when the ignition is moved to the on position does the fuel pump prime (turn on). Has anyone even noticed.

 

I've done a relearn on multiple vehicles and sadly, I never paid attention if the pump primes.

 

question, if the security system is in place will it disable the fuel pump? my car wont start, like it will crank but it wont start, i already ordered a new fuel pump because i checked the pressure and there wasnt any, also when i turned the car to the on position i didnt hear it prime or hum

 

I am pretty sure when it's in theftloc mode, the starter does not try to crank. So I don't think you have a theftloc issue.

 

hey guys so i tried doing this and still no luck. at first i did the relearn for 11min
switch the key to off then it cranks but wont start after that attempt it wont crank again because the security light starts blinking again. so i did the loing procedure repeating all the steps and still no luck.

i think i have a faulty bcm because for a ling time it kept saying door ajar and every time i put a new fuse in the bcm slot on the right side fuse panel in the casr it blows instantly. this bcm prob has been going on for 8 months now and i left it alone since it really didnt do anything and i disconnected the light bulbs in the car so it wont drain my battery overnight.

my pcm is from zzp i did the supercharged kit install and im hoping its not a problem with the pcm. its been working fine up untill now.

im thinkning of getting a new cylinder set and try that out. can i get a key made from the lock smith? or am i going to have to go to the dealer, i noticed there is no security chip on my key.

thanks

 

ON my car I have 4 key positions. Off, ACC, On & Start. Some of these relearn codes say to turn the key to the ACC/On position. But mine are separate. Does that play a part in it not starting? Also, my key is a but worn. Could the security not be recognizing my key, keeping me from starting? Thanks.

 

You need to leave the key in the "on" position. And I have heard of worn out keys creating problems with the car's security system.

 

I had a new key made. But I'm still getting the same result. I really don't want to have to open the entire dash just to modify the ignition cylinder. Right now I don't have the money to pay someone from GM $170hr just to come down & reprogram the security system. Technically it's an antique & I'd just assume disable the security system altogether(if that's possible) & install an entirely new one later down the road. For now, I just want the car to start. This is literally the only thing wrong with the car. It runs great. When I bought it, I was originally looking for a 90' model. But I saw it was a 6 cylinder & thought it would be much better on gas. Still, it has features that some of the newer vehicles don't even have. Very quiet too.
