I've got an even cheaper and easier solution, instead of buying a new cylinder, find that plug and snip the orange wires going to the old cylinder.Then remove the resistor chip from the key and solder each of the the wires to each side. this will fool the car into thinking the correct resistor chip is in place, allowing you to use the original key or any copies with or without resistor chips. i just did this to my caddy and it roared to life! :)

I Have A Seville 1990, When That Happen To Me I Got The Inginion
Replaced Problem Solved. What Is Happening Is Your Key Has A Chip And That Chip Is A Resister And When The Valve Is Not Sented To The Computer It Disengages the Fuel Pump And Than Tells You To Wait. Soon All That Will Happen Is You Will Get The Wait 3 Mins And It Will Never Start, A Good Locksmith Can Take Care Of This For You And That Will Save You Some Money. Cause If You Go To The Dealer Ouch They Will Hit You Up. But I Asure This Is How It Will Happen Cause It Is How It Happen To Me
And Sorry There Is No By Passing The Computer

In the low side fitting near the accumulator tank, R-12 is very $$$$$. convert to R134 to save money if a lot of R-12 is needed if you can find it.

its probably your alternator i would start by testing that im pretty sure advanced can test it for you. also test your battery because when the alternator goes it will run off of your battery and drain it if that doesnt work out for you then your going to have to provide me with further symptoms

sounds like you are low on refrigerant; with engine off, ignition on, press Off and Warmer and hold until everything lights up, let go and write down the codes that appear on the driver information center and post them and we'll let you know what the problem is.

It might be the fan relay switch. When the car gets warm check to see if the fan comes on.

Sounds like it is slightly out of timing or a valve needs adjusted.
