SOURCE: 1993 buick lesabre won't start. security light is

The coded key probably needs to relearn. Turn ignition to crank and release. Let sit in on position (engine off of coarse) for a full 10 min. turn off for 30 sec. and repeat 3 times engine should start. This procedure should take 30 min. so a booster is needed to maintain a full 12 volts. Do not attempt w/out a charger connected;

SOURCE: anti theft system -can't start car

The price is forbidding our small income expenses. . .BUT if you can
determine my explanation below that your bypass is compatible with ours?
We, I, my wife and baby, are confined in the seculed place in Hayfork
mountains. . .I am seeking for main stand-alone switcher that turns off
against fuel pump, against inner dome light, against rear trunk lid light,
against auto transmission and against four door lock actuators . . .I
successfully made it run with bypass starter relay and hot wired down to
gas tank pump and it runs well but "service immediately" light stays on..
and auto transmission starts on 3 rd gear that stalls engine, it wont start
on second gear. . .when arrived home on uphill road it wont go up so I
drove it on reverse and finally parked here. . .
I KNOW it is a few steps ahead where stand-alone switcher are. I am going
to follow the dome light's wire down to the place where relay-switchers
are. . or follow gas pump wire that I assume can be very hard way to do. .
but before I go ahead that if you can tell me where those switchers for
A/T, fuel pump,inner lights, doors are located?? in 1998 SL1 ? that would
really save my searching . . . Your tips without having to purchase your
bypassing kit would be greatly appreciated.
Sincerely, Donald

How to fix 1993 buick parkave if all power works but not starting

When you try starting it I assume it does nothing since you said "all power works". So going off that assumption I'd say, make sure it isn't your battery 1st. Just because you have power to acc. doesnt mean you have enough power to turn your car over. If the battery is not the problem then I would check the ignition which will more than likely be your problem. There are only 2 things before your starter to choose from. The ignition is the box under your steering column with all the wires coming out/to it depending how you look at it. Hope this helps you.

I have 93 parkave and all power works but wont start

The click is an indication of the starter solenoid being defective, the heavy contacts inside are burnt away and making a poor connection, this keeps the starter from getting power from the starter solenoid. You can just remove the starter or you can just replace the solenoid. You need to disconnect the battery negative cable before doing any work. The starter is accessed from under the car, you must make a note of what wires go to what terminal when you remove them, it is a common mistake to not do this and slows the installation because of the confusion over where everything hooks up.

1993 Buick Park Avenue we had a dead battery so we removed and charged it. Now the Car won't start and when I put key in the ignition the security light starts flashing

Any car with a Factory Anti-Theft System does this whenever battery power is lost. If your owners manual doesn't address this, you will have to contact a GM Dealer to get the system reset. Sorry!

Replaced ignition module now it won't run at all

After changing the ignition module, you may have broken the communication between all the components in the anti theft security system. This is common on GM antitheft systems. Check out this link for how it works and solutions to security problems.
