replaced battery in 1991 cad deville and reprogramed computer as car manual said. now car will turn over but not start

Check the 96 Caddys starter solenoid. Also check the wiring between the battery and the solenoid for any breaks or loose connections.

Changing the starter on a 1996 DeVille sedan can be a little complicated for beginners. The intake manifold will need to be taken off the car before the starter can be removed. After the manifold is removed, the starter can be taken off. The wires will need to be taken off the existing starter and labeled or taped for the new starter. The start is held in place by two bolts and after the bolts are removed the old starter can be removed.

Any key bypass system intended for that vehicle. It must be properly installed with remote start system brain.

From the climate control system, which acts as the diagnostic computer. Press and hold the off and warm buttons together. You will see the system 888 then 7.0 then the active codes will start to show. Write them down. You can google amost any code you find.

Its a problem with your traction control. It may be just the switch in the glove compartment. If traction control is turned "OFF" the car will only start in 2nd gear.

Majority of the time the problem is in the ignition key chip or ignition lock cylinder

is the check engine light on? if not then i would start with a tune-up (spark plugs & wires fuel filter air filter pcv valve), i believe that's a Distributor less ingition system so no cap or rotor. also a throttle body service is probably needed. good luck!

probably your security system . Search google for "Bypass GM Vats Security"

Most likely the very fragile wires that read the "chip" in your key have broken. These wires are located just inside the key opening in your ignition tumbler and under go constant twisting. You can bypass the theft system and save alot of money. There are instructions on the internet. Google bypassing VATS on GM cars.

I will assume that is in an automobile. A bypass hose goes around the thermostat in your cooling system to allow some coolant to flow whenever the engine is running. This prevents to much pressure to be built up in the system, allows for even cooling at start up and even gives you a slight amount of heat when you start the engine. Your heater core is often part of the bypass system in a car. When the engine's thermometer opens the flow of coolant in the car increases this cooling the engine. As the engine cools the thermostat closes slightly and increases the flow through the core and bypass hose.

connect another cars battery with jumper cables. Will power the trunk motor, and allow it to be closed once cables are connected ( PROPERLY ). You might even be able to jump start car. Good luck

There is an air leak in the intake system that is allowing air to bypass the throttle body.

yes it can its actually easier because u don't need to bypass factory anti theft system

how do i bypass the security code on my 1995 buick lasabre because my key is bad and i dont want to pay 185.00 for a key

There might be bypass kits available on the internet for your car depending on which security system you have. The only other option would probably be to replace the security system itself.

Turn the key forward for ten min. then shut the key off then try to start it.

02 cadillac deville wont crank or start the entire dashboard illuminates and everything work when the switch is on seems like it wants to crank but doesnt. I had a problem for years with my 1991 Caddy and kept changing starters for a while. My problem was that I wasn't getting a good read on the security chip in the key. Next time it happens: turn it off, take the key out, wait at least three minutes and try again. Check your manual to see if that is still the procedure. By the way I decided to live with it. Every start is a roll of the dice.
