SOURCE: 1999 Buick regal Security light on. Won't start.

A remote starter could be the problem. Have you recently gotten a new ignition key? If you have gotten a new key does it have a chip on it? If so is it the right chip? If no chip on key then that is for sure the problem. As long as that light is on after turning ignition to the on position (not start position) the car will not start when turned to the start position. If this doesn't help you out then submit more information and i'll try to help again.

SOURCE: 91 Buick Roadmaster wont start....... Baffeling

If the engine will not turn over using the starter then it cannot be the fuel pump. If the car has a factory inhibitor system installed, the chances are that it is this system that is preventing the car from starting. You may not have to press a button on the key fob either, it may have a transponder built into the key fob which transmits it's data at switch on.If you don't have the correct key or a key without a keyfob then the anti-theft system will NOT be disabled and the car will not start. There is no easy answer for this as you need the correct keyfob or you need to purchase and have programmed, the new keys.. If this is not the issue, let me know and I will describe further procedures for your issues..

93 buick regal 3.8 codes 26QMD &42EST PLUS POOR GAS MILAGE


Code 26 is for a problem with one of the quad drivers inside the engine computer, or the wiring harness, and code 42 is for a problem with the ignition module or the control.
You'll need a shop manual with the testing procedures for each code to proceed.

The quad driver is in the computer it drives the fuel injecters. you could have an injector problem if one injector shorts it will cause the code to show up you can ohm the injectors and find the problem e-mail me and let me know what you find Phil
