Hay bigtoe555, welcome to AF!

Saying that it will not "start" leaves out a few items. It could mean that the starter doesn't turn the engine over, or the starter is working but there isn't any spark or fuel to make the engine run. Please let us know which problem you're having.

i'm sorry i said i get all the lights on the dash but the do not try to ingage,no power to the starter does not try to turn over i think it's something to with the code even with the security light goes out

Are you using the key that came with the lock cylinder?

Is it of the same resistance as the old cylinder?

Sounds like you have a VATS (Vehicle Anti Theft System) problem.

If you search this board, you'll find how to bypass this system with some resistors and not have to spend $25 for a spare key.

If you replaced the key along with the cylinder, it does not have the same resistor chip in it. You will need to find out what the resistance should be, which is not easy when you dont have an original key. You will need to figure out which resistor by trial and error.

that's my problem yes it is the key that come with the cylinder but i had to get a key cut for the code of the computer which it say is code 7 but i don't think it is the right code i had dealer look it up for me and i yes did search the forum for help but did not see how to bypass it i will look again thank you

ok i got the car to start with a 4.7 ohms resistor so what code should i use to get a key made with and thank for help:grinyes: :grinyes:

"4750" would be one of the 15 standard GM resistor key blanks.

i had a key made today and everything is works ok i would like to say again thank you guys for all the help:grinno: :grinno: :grinno:
